Description

A densely insulated busway

technical field

The utility model relates to a densely insulated bus duct.

Background technique

A plurality of busbars are arranged in the busway to transmit electric energy and have the function of collecting and distributing electric power. Through it, the electric energy output by the generator, transformer or rectifier is transmitted to various users or other substations. Because the bus duct carries large current and high voltage during the power transmission process, the bus duct products have extremely high requirements on insulation performance, fire resistance and waterproof performance, but the existing bus duct is still difficult to meet the fire resistance and waterproof performance. performance requirements.
