 Normal conditions of use1,The altitude does not exceed 1000m.2,The ambient air temperature:Maximum+40°C;Minimum:General Area-30°C ,paramos-40°C .3,The wind pressure does not exceed 700Pa(corresponding to 34m/s wind speed).4,The earthquake intensity does not exceed 8 degrees.5,The working situation without frequent violent vibration.

 Installation Note

The installation site of ordinary  isolator should be away from gas,smoke chemical deposition,salt,spray fog,dust and other expiosive and corrosive materials that affect seriously insulation and conuction capability of the isolator.Pollutionproof type isolator is apples to severe filthy conduction area.however.It shouldn' be any explosive matters and matters causing fire
