9 4 Introduction The body of this specification covers general design and construction requirements. How to construct and maintain ABC is detailed in a separate manual known as the Overhead Line Construction Manual. Appendix A to Appendix C of this document comprises General Arrangement (GA) drawings with associated lists of materials for LV ABC structures as follows: 1. Appendix A comprises GAs for LV ABC distribution networks supported on wood poles. (Note that inside and outside angles are not as defined in ENA TS ) 2. Appendix B comprises GAs for LV ABC service connections, followed by a GA summarising ABC and CNE service spans 3. Appendix C comprises GAs for LV ABC pole-mounted equipment. Each list of materials identifies the components included in the associated GA and which supplementary items are needed to complete that structure. Variations within each GA for different conductors are covered by different columns in the associated list of materials. Note that the lists of materials for the connections and plant shown in Appendix B and Appendix C do not include the materials for the associated GA structure; many combinations are possible and it is not practical to cover every possible structure/connection variation here. (Refer to Appendix A for approved GA structures and materials.) Appendix E Reference List of all Materials for this specification comprises a reference list of all materials used within this specification. Appendixes F to M are tables of design data for this specification: one Appendix for each ABC type. This specification fits into the overall design and construction process as outlined by the following process summary: (a) Carry out a risk assessment. (b) Generate a proposal taking into account the risk assessment. (c) Generate a proposal for a new line. (d) Choose a proposed route and a line survey carried out. (e) Plot pole positions, heights, clearances, and develop a line profile. (Note that the development of a line profile will require some data and parameters from Appendix F and subsequent Appendices.) (f) Compile a list of materials using the GAs and supplementary items identified in this specification (Appendix A, Appendix B, Appendix C and appropriate ES and/or ENA TS). The GAs and supplementary items shall be selected and used in accordance with the design and construction information given below and the data given in subsequent Appendices. August 2012 OHL Design Manual - Section 1 - Aerial Bundled Conductor (ABC) Low Voltage Mains And Services LS BH PW Page 9

10 Appendix M provides a table to give distances in metres from pole base to stay base dependant on pole size. This has been provided to support the minimum angle of stay column provided in Appendix F to J. 5 Design Information 5.1 General Practice Lines shall be designed using the GAs and supplementary items from Appendix A, Appendix B, Appendix C and the data from Appendix F to M, etc. The following information shall be taken into account during the design process. 5.2 Risk assessment A risk assessment shall be carried out at the commencement of the design work to identify the site specific safety hazards. The design shall incorporate mitigation measures to control the risks, identified in the risk assessment, associated with the construction, operation and maintenance of the proposed overhead line and its suitability compared with an underground cable solution. 5.3 Earthing System earthing shall meet the requirements of the current UK Power Networks LV Network Earthing Design Manual EDS To provide a PME network the connection from the neutral of the bundle to the earth electrode(s) shall be installed and connected in accordance with the drawings given in Appendix D. (The PME connections are split across two drawings, because all pole mounted equipment GAs incorporate connections from bundle neutral to neutral/earth as mandatory requirements.) 5.4 Design Data Each set of design data (Appendix F to M) contains all the information necessary for the conductor bundle specified, with the exception of poles supporting electrical plant. Design parameters used to construct the tables of design data are given for reference. Note that the basic span for this design is 50m. If ABC is to be installed onto an existing pole it is then assumed that the pole depth will be 1500 mm. The maximum wind loading span shall then be limited to the figures supplied in Table 6 and Table 12 (Appendix F and G). If an existing pole has to be changed due to decay or clearance problems then refer to tables for planting depth for new build. March 2011 For poles supporting electrical plant, strut loadings need to be re-calculated as necessary. (Note that 1000kg additional weight can be approximated to 1000kgf additional loading for this purpose.) Data in Appendix F to J, etc, are based on the minimum pole diameters included in BS In practice, if it is found that strut loadings exceed the values given in Appendix F to J, etc, the minimum pole top diameter needs to be re-calculated. Maximum service spans shall be in accordance with Figure 15: Concentric Service Spans and Figure 16: ABC Service Spans. Overhead Line Design Manual Section 1 LV ABC v1.2 Page 10

12 6 Construction Information 6.1 General Practice Construction practices shall be in accordance with the UK Power Networks Overhead Line Construction Manual. For reference, ABC phases and neutral shall be identified by the number of ribs on the insulation as follows: Phase L1: 1 rib. Phase L2: 2 ribs. Phase L3: 3 ribs. Neutral: fully ribbed. (Note that this applies whenever ABC is used; e.g. when neutral is run down the pole for connection to the neutral/earth connection.) Supports All fittings supporting the ABC system shall provide an insulating barrier rated at 1000V between the core insulation and the mechanical attachment. The ABC shall be attached in such a manner that it cannot make contact with any metalwork or stays. The maximum pole height for a service or service line shall be 9 metres. Weak links will be used on all poles except for the following: 1. Terminal poles 2. Section poles or 3. Either side of a road crossing. 6.2 Clearances General Clearances from external objects and structures (e.g. buildings, trees and roads) shall comply with ENA TS In-line construction clearances shall comply with those specified in the specific job instructions detailed in the Overhead Line Construction Manual. In addition to the above, the following rules shall be followed: March Wherever possible, ABC conductors shall not pass directly over buildings and roofs. 2. Wherever it is necessary to over sail a building or roof, the relevant span shall not contain any in-line connections. 3. Where ABC is attached to a building which has a thatched roof, the attachment shall be a minimum of 0.5m from the thatched roof. 4. Once terminated, ABC shall be converted to concentric cable or insulated and sheathed (mechanically protected) cable within 0.5m of the point of attachment to a Overhead Line Design Manual Section 1 LV ABC v1.2 Page 12

13 building. Service cable lead-ins into the building shall be installed in accordance with the Overhead Line Construction Manual Tree Clearances Where an ABC system is erected through trees, the following points shall be considered: 1. For additional information regarding overhead line clearances, refer to ENA TS Risks of the ABC being abraded by trees. 3. Sag variations and conductor swing due to the effects of the wind. 4. The effect of wind and snow loading on trees or branches bearing onto the ABC. 5. The danger of trees providing climbing access. 6. The amount of tree cutting required for ABC compared with conventional open wire systems can be significantly reduced. However, the XLPE insulation is susceptible to abrasion and shall not be allowed to come into contact with tree trunks, mature branches or heavy outer growth, under any circumstances. 7. Clearances through trees shall take account of maximum and minimum conductor sags, conductor swing and the anticipated tree growth rate and cutting periods. 6.3 Low Voltage Supports All supports shall be fitted with a Safety Sign (Danger of Death) in accordance with UK Power Networks EDS Augering Augering the pole hole is the preferred method when the ground is suitable. After pole erection, the remaining hole shall be backfilled with suitable material based on soil condition. If there is a risk of movement due to poor soil conditions then a suitable cement mixture shall be used. 6.5 Foundations Un-stayed angle poles shall be installed 0.5m deeper than the planting depth given in the Appendices to this specification. (Care shall be taken when planning un-stayed angle poles, particularly near walls.)

14 6.6 Stays Only the following types of stay are suitable for lines designed to this specification: Load-lock anchors (Light) Screw-in (Heavy) Concrete blocks: Light 500 x 300 x 90mm Heavy 640 x 430 x 140mm Refer to tables for staying arrangements. Heavy duty stay plates are useful for structures of restricted height: the overall distance between the fixing at the top of the pole and the stay insulator is less than that of an equivalent pole-top make-off. March 2011 The distance of the stay-base from the pole-base are given in Appendix F J using angles in degrees from 0 o to 45 o measured between the pole and stay. This information is then supported by a further table 42 provided in Appendix M which gives the spread in metres between the stay and the pole at ground level. 6.7 General back-filling and Compaction All holes shall be backfilled with the excavated material but consideration should be given to soil condition. It may be necessary to import suitable material which can be mixed with a cement based compound for reinstatement around the pole. Overhead Line Design Manual Section 1 LV ABC v1.2 Page 14

15 Any poles erected in the highway (excluding grass verges) shall be backfilled with suitable material with reference to NRSWA requirements. 6.8 In-Line Connections Compression fittings shall be used for all tension and in line non-tension connections. (Under no circumstances shall IPC s) be used to make in-line connections.) 6.9 Connections to the Bundle General Only ABC to ABC connections to the conductor bundle are permitted.
