Polymer Air Break Switch Three Phase
Brand :RUILY
Product origin :CHINA
Supply capacity :5000 PCS/ month
The outdoor type high voltage Air break Switch is suitable for power system with rated voltage 10KV to make or break power supply under circumstances of with voltage and nonload .The isolator use isolated hook stick to operate .
The environment of working can be as below :
The altitue boes not exceed 1000m
the ambient air temperature :General Area Maximum +50 ℃ ； Minimum ： -40℃
The wind pressure does not exceed 700 Pa (corresponding to 34m/s wind speed).
The working ituation without frequent violent vibration .
The installation site of ordinary type is isolator or should away from gas, smoke chemical deposition ,salt-spray fog,dust and other expiosive and corrosive maters that affect seriously insulation .
Pollution-proof type isolator is apploes to server fifty conduction area .However ,It should not be any explosive matters and matters causing fire .
