HT Switchgear

The VCB, MOCB, LBS, SF6 circuit breaker and the switch boards are of optimized design for Bangladeshi supply condition and ambient. The breaker and switchboard is of compact design, sturdy construction and simple in operation with a proven motorized spring operated mechanism. This design ensures ease of operation, low cost maintenance and higher longevity. We are also using very high quality ring main unit (RMU) suitable for highly populated city like Dhaka for multiple feeders in incoming and out going.

 HT Panels are equipped with Built-in mechanical interlocks for safety and the breaker compartment is so designed, that it ensures the inter changeability with the identical circuit breakers. The cubical design of 12KV, 25KV, and 1250A is also compatible with our SF6 and minimum oil circuit breakers (MOCB). The panels are fully compartmentalized and extensible on both sides, consisting of bus bar chamber with adequate air clearances, PT compartment, CT and cable termination compartment, breaker compartment and metering chamber.

Type of HT Switchgear: 

VCB/LBS/SF6 breaker is suitable for use in cubicle switchgear units. Such breaker is fixed to a switchgear or floor by bolting its base with it. If 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 connections to various positions are made in the following manner:  

Main connection – by bolts 
Control connection – by screws 
Earth connection – by screws
