Mechanical operations The mechanical endurance tests on all the operating parts ensure the reliability of the circuit breaker. General experience in the electro-technical sector shows that mechanical faults are one of the most common causes of a fault in an installation. The circuit breaker is tested by carrying out a high number of operations - higher than those which are normally carried out by installations in the field. Furthermore, the switchgear components are part of a quality control program and samples are regularly taken from the production lines and subjected to total mechanical life tests to verify that the quality is identical to that of the components subjected to the type tests. Base Frame An optional 75mm height base frame can be provided with SecoGear. The base frame can be used on up to 5 panels to provide modular concept for the switchgear. Use of the base frame decreases field work for mechanical and electrical assembly hence decreases the total commissioning time by up to 80%. Base frame usage is highly recommended for marine and E-House applications. IP degree The IP protection degree is the resistance offered by SecoGear against penetration of solid objects and liquids. This degree of resistance is indicated by the prefix IP followed by two characters IP 4X is for the enclosure and IP 2X for the partitions. The first number identifies the degree of protection against the entrance of solid objects, the second one is related to liquids. IP41, IP42 and IP43 are available by customer request. g 10.000 1.0000 0.1000 1.0000 Zone4 [SRS] Minimum (1.0,3.63974E-001) Maximum (2.454353,2.5735E+000) Marine application Approvals American Bureau of Shipping (ABS) Seismic Certification UBC Zone 4 Seismic Certification- IBC 2012 Inclination The Inclination test proved that SecoGear can continue operating as intended, even when inclined at an angle up to 25 degrees on all four sides and with an ambient temperature of 50 C, IP42.

SecoGear FA 17.5kV is 100% compatible with standard SecoGear 17.5kV panels. High ambient temperatures The service conditions for the electrical circuit breaker in marine installations are generally more severe than those in normal land applications. Temperatures are a main factor and for this reason the shipping register regulations require the switchgear to be able to operate at higher ambient temperatures of 40 C or higher. The operating conditions on marine platforms and shipping installation require the capability to work in environments affected by vibrations. SecoGear was exposed to a resonance search and endurance random, which consists of a random vibration test according to IACS E10.

Environment Increasing global legislation concerning the use of green - house gases such as SF 6 gas and their related disposal costs, makes vacuum technology with its reliability, low maintenance, and low environmental impact the choice for now and the future. As the world strives to reduce the amount of SF 6 gas used in all applications there is a responsibility on the users of electrical switchgear to find, where appropriate, alternatives to SF 6 gas as an insulation and switching medium. Air and solid insulation switchgear systems incorporating vacuum switching technologies are a reliable, safe and economic alternative for use in electrical systems below 36kV and therefore should be used instead of SF 6 gas insulated systems. Modern medium voltage switchgear employing vacuum technology together with air and epoxy resin insulation provides: Minimum number of parts and components No special requirements for the end-of-life disposal of the switchgear Environmentally-friendly materials used in the design No use of SF 6-gas for switching and insulation No risk of damaging leaks of SF 6 gas or of toxic byproducts Energy-efficient production and assembly, with environmentally friendly energy sources Minimal number of transition points in the primary design enables low energy loss during operation Only re-usable and/or recyclable materials used Product Description Environmentally friendly design GE's production plants act entirely in accordance with the rules and procedures of the ISO 14001 environmental certificate during development and production processes. Material selection and the number of parts that are used to manufacture the SecoGear are critical to determining how environmentally friendly the manufacturing process is. GE selects its materials to ensure that they have the lowest possible impact on the environment. It is essential that they are equally safe for people not just during use, but at the end of service life too. Within SecoGear and the SecoVac vacuum circuit breaker, a combination of solid (cast-resin) and air is used as insulation. The castresin technology, in combination with electrical field calculations, provides a very compact, environmentally friendly design for the circuit breaker and the switchgear. Because the switching medium - vacuum is used, SecoGear can be completely recycled at the end of its life without any issues relating to safety procedures, special handling or safe disposal. 13

Environmentally friendly Energy efficient assembly From the very beginning GE made a SecoGear is produced in an energy fundamental choice not to use SF 6 as efficient environment. Standard a switching and insulation medium for processes and materials are used in the primary medium voltage equipment. SF 6 design and require no special handling is on the list of greenhouse gasses in the or manufacturing processes, thus Kyoto protocol and is the most potent reducing the amount of energy required of the six main greenhouse gasses, with to manufacture and assemble the a Global Warming Potential (GWP) of switchgear. Product Description Environment 23,000. Many other medium voltage switchgear systems use SF 6 gas as the insulating medium. Leakage of SF 6 gas from switchgear contributes significantly to the threat of the greenhouse effect and associated climate change. They also require additional safety measures and special handling requirements at the end of life. Minimum service checks on site SecoGear is designed for a lifetime of at least 20 years; therefore the energy usage for maintenance activities during this long period is minimal. Due to the green insulation and switching technology, there is also no leakage of the harmful SF 6 gas during its lifetime and no need for performing extra maintenance activities on SF 6 gas pressure checks. Minimal energy loss during operation The number of electrical contact or changeover points within the SecoGear system has been kept to an absolute minimum. This reduces the potential number of "hot spots" and prevents additional energy loss associated with contact surfaces. Efficient use of materials Besides the energy sources, special focus is placed on the efficient use of material during assembly. For example by using advanced nesting tools the hot dipped galvanized steel plates are cut with the least amount of waste, and similar principles are followed in the design and manufacture of other product components Re-use or recycling of materials All materials of SecoGear and SecoVac can be reused, all materials are not any impact on the environment, it fully reflects the GE corporate social responsibility to design and produce products. 14

It is connected between primary conductor and ground for protecting protective load from damage effect. When the operating or lightning over-voltage occurs, surge arrester immediately limits over-voltage amplitude and protects the insulation of device. Disconnector Truck Disconnect truck is used to disconnect primary circuit and normally coupling with busbar tie breaker to achieve two section power supply. Disconnector truck can be provided with bus tie/riser panels.
