Turnkey 145 kV S/S project for Borlänge Energi, Sweden, emphasizing the advantages of ABB Disconnecting Circuit Breakers. Small footprint enables indoor air insulated Switchgear solutions, increasing the power substation availability and reliability for the customer.
As a complement to the basic version of our LTB circuit breakers, which are primarily designed for conventional substation solutions, there is a disconnecting circuit breaker configuration with the disconnecting function integrated in the breaking chamber.
The LTB Disconnecting Circuit Breaker (DCB) is based on the LTB standard circuit breaker. The disconnecting function is integrated in the breaking chamber. That means that the circuit breaker fulfills all requirements for a circuit breaker as well as all requirements for a disconnector. A safe interlocking system, composite insulators and a motordriven grounding switch provide personal safety.
With DCB we have created the capability to design substations without conventional disconnectors, which improves operational availability.

Hi, I'm an electrical engineer, programmer and founder of EEP - Electrical Engineering Portal. I worked twelve years at Schneider Electric in the position of technical support for low- and medium-voltage projects and the design of busbar trunking systems.I'm highly specialized in the design of LV/MV switchgear and low-voltage, high-power busbar trunking (<6300A) in substations, commercial buildings and industry facilities. I'm also a professional in AutoCAD programming.
