Selection
Operating conditions
1. The altitude above sea level: 2000m
2. The ambient air temperature: -40℃~40℃ wind speed does not exceed 35m/s.
3. The earthquake intensity does not exceed 8 degrees.
4. The working situation is without frequent violent vibration.
5. The installation site of ordinary type isolator s hould be kept away from gas, smoke chemical deposition, salt-spray fog, dust and other explosive and corrosive maters that affect seriously insulation and conduction
capability of the isolator .
6. Pollution i-proof type isolator is applicable to severe filthy conduction area, however, it shouldn't be any explosive matters and matters causing fire.
