Red Color Switchgear Epoxy Resin Cast Bushing Heat Resistance 4000A 10kV

CHN3-12Q/280 4000A 10kV Epoxy Resin Insulators Contactor Box Spolt Bushings

Gas, Steam, dust without seriously affecting the insulation of the contact box

No exploration or corrosive submission.

Technical Data & Requirements Requirement Technical data and requirements 1. Contact box and contact should be able to withstand frequency test voltage(effectiveness) 42 KV, 5 minutes, lightning shock(peak) 75 KV;

The label contact to earth call with power freedom test volume of 42 KV for 5 minutes and
Lightning impact vplage(peace value) of 75KV;

The temperature rise of the end of the contact box at the end of the line under long-term operation does not exceed 65 ℃ under the rated electricity;

The experience of lead-out final call not more than 65 °C if the contact box is used for long time in rate current con the wall-piercing sleeve is used to increase the insulation function of the mother-row in the cabinet and play a certain supporting role. In the middle, in the end.
Insulators only act as support, sometimes using a belt point sensor directly instead of an insulator as well as as as sensors.

The cabinet is large but easier to maintain. Medium case is large, but maintenance is more convenient. Ring case is small, but maintenance is not convenient.(Schneider SM6 now has a high voltage loop switch cabinet with special SFset circuit breaker. SGN1A-12(Z) small fixed separator, developed jointly, can achieve the basic function of medium case using ABB LEG(Z1)-12 circuit breaker, but the ring net case or small fixed compartment can be set up as a low voltage circuit breaker. Only according to the fixed mode of installation, so that when the circuit breaker failure, need to be replaced immediately, not only need to cut off the upper power supply, but also trouble to replace. It is convenient to replace the handcar switch.
