Product Details

Load Break switch is a common piece of equipment in an electrical substation to turn off and on the power to the transformer. It is used to isolate the substation from the distribution incoming line. Generally, a 12 kV load break switch is placed before a 12kV/415V transformer so that in case of a shutdown, it can be turned off and the main distribution line to other users does not interrupt. It is a mechanical switch protection system that is cheaper than a Vaccum circuit breaker. There are two types of LBS currently available in the international market. One is Air-insulated LBS, most of the LBS user clients in Bangladesh use this type of LBS . Air-insulated means the switching system is operated in a medium surrounded by air. Another one is gas-insulated LBS which is fairly new to this industry. In Gas Insulated LBS the switching operation is done in a closed chamber with a gas having high dielectric properties such as SF6 gas. Simtech Engineering is the biggest Local supplier of Air-insulated LBS in Bangladesh. But recently we have launched a new Gas Insulated LBS as well.
