Product Description

IACM with polystyrene insulation  Outdoor Load Break Isolate Switch

General	LBIS Type outdoor on load break switch disconnector contained in this list are destined to switch stub lines and ring main lines or transformers (It can be equipped with MV HRC fuse links as short circuit protection fuction) or for switching under on load conditions. This disconnector complies with IEC/IEEE and DVE-recommendation standards especially comply with DIN VDE 0670 part 3 and IEC 60265, IEC 129.
Features	All steels are made of either in stainless steel or hot-dip galvanized steel.  1. Solid and stable base frame.  2. main contact with ice protection.  3. Polymer insulators or alternatively in porcelain.  4. Minimal sag for the line-connection between two fixed terminals.  5. Completely maintence antirust Aluminium alloy Arc chamber.  6. Switching-off procedure without external arc.  7. Short circuit making capacity under specific conditions possible  8. Fixing on the supporting structure either by clamping(free setting) or screwing (holes in the   base frame)  9. Easy on-site installation and setting.  10. High reliabilty up to 1000 cycles (depending on the running current).  11. All contacts are either sliver or tin-plated.  12. Practically maintance-free.
Environmental   Conditions	Ambient Temperature: -40ºC - +50ºC   Altitude: 2500m  Frequency: 50Hz / 60Hz  Maximum Wind Speed: 35m/s

Isolating Switch 

An electrical device for the reliable disconnection of certain sections of a high-voltage electrical network when there is no current in them. The use of isolating switches (either alone or in combination with high-speed short-circuiting devices) makes it possible to simplify the arrangement of switching points and transformer substations and to eliminate expensive high-voltage circuit breakers.

 

In the case of damage to certain sections of a network, the circuit breakers operate first, and then the isolating switches automatically disconnect the damaged section, after which the circuit breakers close again and restore electric power to the rest of the consumers on the network. Isolating switches are also used to disconnect and reconnect unloaded transformers and sections of power lines during operation. An isolate switch must provide a reliable connection in case of a random occurrence of a short circuit in the network. An important characteristic of an isolating switch is a short operate time, particularly the disconnect time, which must not exceed 0.1 sec.
