Product Description

Product Description

It is characterized by safe,economical and reliable and broadly used in places such as power plants,substations,industrial and mining enterprises,mines,stations and hospitals.
Its characteristics include high breaking capacity,good thermal stability,flexible electric schemes,easy assembly,strong series and practicability and novel structure.
The rated current can be increased to 3,150A to match the distribution transformers of under 2,000kV.
Electric components in the unit are mainly products that are produced in batch with stable process.Imported products are applicable as well.
HD13BX and HS13BX rotary-operation knife switch is a special element that is designed to meet the unique structure of GGD unit.As practical electric components,they change the operation mode of mechanism and maintain the advantages of old products.

Bus-bar clamp is thermoformed from PPO alloy materials of high strength and fire resistance,with high insulation class and good self-extinguishment.
The frame is locally welded and assembled with 8MF cold forming sectional steel.
Electrostatic epoxy powder (international gray)is used to coat the unit surface,with strong adhesion strength and good texture.Degree of protection of unit is IP30.Users may choose from IP20 to IP 40 based on their environment conditions.
