Description:
HJDW6 outdoor low-voltage switch is a single-phase AC 50Hz low-voltage switchgear for power system with rated voltage of 0.5KV, which can be used to connect or isolate the power supply when there is voltage and no load. This knife switch is operated with an insulated hook bar.
This knife switch is a single-phase structure, and each phase is composed of mounting plate, pillar insulator, switch blade, contact and other parts. The upper end of the knife has a fixed pull ring for the insulation hook rod to be used for separation.
Use environment:
a. The altitude does not exceed 1500 meters;
b. Ambient air temperature: upper limit +40 ° C, the lower limit is generally -30 ° C;
c. The wind pressure does not exceed 700pa (equivalent to wind speed 34m / s);
d. The seismic intensity does not exceed 8 degrees;
e. No frequent and severe vibrations;
f. Ordinary installation sites shall have no gas, vapor, chemical deposits, salt spray, dust and other explosive or aggressive substances that seriously affect the insulation and conductivity of the knife switch. The anti-fouling type is suitable for heavy pollution areas, but should not cause fire and explosive substances;
