High Tension Switchgear (HT) comprise the units designed for rated voltage of 12kv, 33kv current range 400A to 3200A. Switchgear insulation designed to withstand rated voltage is also subjected to over voltage due to lightning and breaker operation transients. Depending on the conditions switchgear installation are designed and manufactured for outdoor and indoor service. Suitable for mass production, transportation handling and convenient operation, the weight of the equipment is kept as low as practicable. The LBS, VCB, SF6 circuit breaker and the switchboards are of optimized design for local supply condition and ambient. This design ensures easy of operation, low cost maintenance and higher longevity. The cubical design of 12kv, 33kv, and 1250A is also compatible with our SF6 and Minimum Oil Circuit Breakers (MOCB). The panels are fully compartmentalized and extensible on both side, consisting of busbar chamber with adequate air clearances, PT compartment, CT and cable termination compartment, breaker compartment and metering chamber. |

| DRAW-OUT TYPE HT SWITCHGEAR | ||||||
| The complete unit may be provided with a shutter of front cover. VCB/SF6 breaker is mounted on a cradle. This SF6 breaker /VCB along with the cradle can be easily installed inside a switchgear compartment without any need of mechanical adjustment. The interlock of the draw out mechanism type and its special features are– The circuit breaker cannot be placed in or withdrawn from its cradle when it is in closed position.- The circuit breaker cannot be operated as the time of inserting in the cradle.- The circuit breaker & other components like CT, PT, IDMT relays all are imported from USA, Germany, France, UK and Japan or as per choice of our valued customers. |
||||||
| FIXED TYPE HT SWITCHGEAR | ||||||
| LBS/VCB/ SF6 breaker is suitable for use in cubicle switchgear units. This breaker is fixed to a switchgear or floor by bolt with it’s base with it. On requested, fixed mounting SF6 breaker / VCB / LBS’s may be provided with wheels which will make its movement easier. Connections between the breaker and incoming as well as outgoing bus bars, are made directly and kept fixed. The terminal arrangement of a fixed mounting breaker is such that connection to various positions are made in the following manner : – Main connection made by bolts – Control connection made by screws – Earth connection made by screws |
