Special phase barrier plates of fibrous glass reinforced plastic enable a switch panel width of just 00 mm at a rated voltage of kv. Switch panels of Type W are available in two standard designs: W 0 and W 0. The main dimensions of the panels are W x D x H: 00 x 00 x 00 or 00 mm. They can be delivered as individual panels where their equipment, panel sequence etc. can be determined by the customer. Operating Conditions The switch panels of type W are installed in closed electrical operating areas which are only to be entered by skilled personnel and appropriately instructed persons. The installation can be implemented up to an altitude of 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 panels are designed for use under normal operating conditions in compliance with EN. Technical Standarts The design of the airinsulated switch panels corresponds to the specifications of the EN 700. The resistance to accidental arcs of the switch panels has been determined at ka; s by an independent testing institute. The installed switchgear electrical equipment are designed in compliance with EN 7. The degree of protection of the switch panels corresponds to IP x. For technical data on the installed switchgear equipment please refer to our brochures: for switchdisconnector H see 7 for earthing and disconnecting see 7 for circuit breakers see 7 and 77

Connecting cables are introduced from below into the switch panels where they are attached to the provided fastening straps. All builtin switchgear equipment can be manually operated with closed panel door. The switch panel housing The framework of the switch panels is of a welded angular steel design. The switch panels are fitted with a singlewing door of solid steel plate with door hinge optionally on the right or on the left. A window of compound glass is inserted in the door. The cover in front of the bus bar area is either screwed on (Type W 0) or designed as a door for the relay box behind (Type W 0). This relay box has the dimensions W x D x H: 00 x 0 x 8 mm and can be fitted with one or several protection relays, as required by the customer. The corrosion protection of the framework, doors and covers as well as the end covers on the side of the switchgear is provided by structural paint (color RAL in accordance with customer's request). The partition of the busbar area bordering the next panel is in the form of fibrous glass reinforced plastic plates with leadin openings. Each switch panel has a boltedon rear wall of galvanized sheet metal. Pressure relief is in upward direction. It is possible to insert an insulating protective barrier (in compliance with DIN VDE 08, Part ) with the panel door closed. Equipment The switch panels of Type W 0 can be designed as cable or transformer feeder panels or also as circuitbreaker panels. For this purpose they are fitted with switchdisconnectors or fuseswitchdisconnectors (Type H ) to which a shortcircuitproof earthing switch with quickmake operation can optionally be attached. Switch panels of Type W 0 can be designed as cable or transformer feeder panels as well as circuitbreaker panels. These are fitted with a bus disconnector, a vacuum circuitbreaker as well as a set of current transformers. The equipment can optionally be supplemented by an earthing switch and a set of voltage transformers. Spherical fixed points are available as an alternative for earthing and shortcircuiting. Switchdisconnectors and earthing switches are mechanically interlocked, if so requested by the customer. It is possible to install corresponding surge voltage protectors in the panel, if required. A special measuring panel equipped with current and voltage transformers completes the program. The interlocking conditions are in compliance with DIN VDE 070, Part. Insulating protective barriers This insulating protective barrier is to prevent an impermissible approach or accidental contact of live parts. It is to be inserted with closed door if work is to becarried out on the panel and the unit cannot be completely switched dead. The barrier can be removed again by pulling at the grip hole.
