Medium voltage switchgear type W rated voltage kv rated current 0 A
General The metal-encapsulated, air-insulated medium voltage switchgears, type W are for universal application. They range from compact ring cable switchgears up to complex power distribution switchgears. Tailored to meet the needs of public utility networks and power supply companies in industry and municipal buildings. These medium-voltage switchgears meet the user s specific requirements in full and ensure a satisfactory power distribution. The W standard types are available in three different dimensional sizes: W 0; w x d x h: 00 x 0 x 00 mm, W ; w x d x h: 0 x 0 x 00 mm, W 0; w x d x h: 00 x 0 x 00 mm. They are available as individual s or as a combined switchgear, where the equipment, sequence etc. can be determined by the customer. The switch s are type-tested in compliance with EN -00. Operating conditions The switch s of type W are installed in closed electrical operating areas which are only to be entered by skilled personnel and appropriately instructed persons. The equipment can be used at an altitude of up to 000 m above sea level. For installations above an altitude of 000 m the rated insulating level of the switchgear must be corrected accordingly. The switch s are designed for use under normal operating conditions in compliance with the standard EN -. Technical standards The design of the air-insulated switch s corresponds to the specifications of the EN - 00. The resistance to accidental arcs of the switch s has been determined at ka and 0 ka; s, by and independent testing institute. The installed switchgear equipment is designed in compliance with EN -.

The switch frame is made of a screwed, hot-galvanized composite structure. The front of the switch s has a single-wing door of steel sheet with door hinge optionally on the right or left. A window of compound glass is inserted in the door. The cover in front of the bus bar compartment is either screwed on or designed as a door for the relay box positioned behind it. Each switch has a screwed on rear of galvanized sheet metal. Connecting cables are conducted into the switch s from below and are mounted on cross rails. The doors and covers of the switchgear are painted in structural paint (available in different colours according to the customer s request).
Equipment The switch s of type W are available in the following versions: Cable switch WK Transformer feeder WT Measuring switch WM Bus sectionaliser WÜ Circuit-breaker WL All switch s are partitioned off from to, in the bus bar area, by means of fibrousglass reinforced plastic plates with lead-in openings. Pressure relief can be in upward or downward direction. Switch s equipped with load-break switches can optionally be fitted with an earthing switch as well. Integrated in the circuit-breaker, type WL, there is also a bus disconnector. It is also possible to equip these s with a set of current transformers and voltage transformers as well as with an earthing switch. The optional interlocking of the equipment practically rules out any form of incorrect operation. All built-in switchgear equipment can be operated manually or via motor-operated mechanisms when the door is closed. The product program is completed by special measuring s which are fitted with current and voltage transformers. Earthing switches or spherical fixed points are available for earthing and shortcircuiting. An insulating protective plate can be inserted when the door is closed. It is possible to install appropriate surge voltage protectors in the, if required.
