Product Description
Product DescriptioniSC6 SF6 Load Break Switch
MV Indoor switch disconnector
1) Description
iLBSkit is a switch or switch combination is suitable for compose air insulation ring main unit for up to 36 kV.
iLBSkit is designed for indoor applications, and meets requirements concerning human safety as well as ease of installation, operation and protection of the environment.
2) Feature- Upgradability
- Compact
- Maintenance
- Easy installation
- Ease and safe to operate
3) Standards
iLBSkit units meet following standard: IEC62271-103/ IEC 62271-102/ IEC 62271-200
4) Dimensions and weights
| 36KV 630 A switch - 630 A disconnector (width 750 mm) | Weight: 75 kg |

5) Switch or disconnector and earthing switch
Gas tightness
The three rotating contacts are placed in an enclosure filled with gas to a relative pressure of 0.4 bar (400 hPa) for iLBSkit 12-24 kV and 1 bar (1000 hPa) for iLBSkit 36 kV. It satisfies "sealed pressure system" requirements and seal tightness is always factory checked.
Operating safety- The switch may be in one of three positions: "closed", "open", or "earthed", representing a natural interlocking system that prevents incorrect operation. Moving-contact rotation is driven by a fast-acting mechanism that is independent of the action of the operator.
- The device combines the breaking and disconnection functions.
- The earthing switch placed in the SF6 has a short-circuit making capacity, in compliance with standards.
- Any accidental over-pressures are eliminated by the opening of the safety membrane, in which case the gas is directed toward the back of the unit, away from the operator.
