Product Description

Outdoor Load Break Isolate Switch

Product Description

Circuit Breakers & Switch /Isolating Switch   LBIS type

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
