Product Description

Characteristics:

Overall high-pressure injection molding and good sealing performance
Good thermal performance, with large overvoltage energy absorption capability
Outer insulation resistance to galvanic corrosion, anti-aging and high tolerance
Due to solid structure, when serious arrester overload, no gas rapid expansion, with explosion-proof performance
Small size, lightweight and saving floor

High tensile strength, impact-resistant and transport without damage, most appropriate places:

Serious filthy places
Special places explosion-proof requirements
Compact switchgear
Preventive inspection difficult, not to maintain place

Conditions of use:

An altitude of not more than 2000mm
Ambient temperature: -40 to +40℃
Power frequency: 48 to 62Hz
Indoor and outdoor common

Prevention and testing: before being put into operation or use two years later, preventive tests should be done before test arrester on electrical equipment should be removed

Inspection items and methods are as follows:

Leakage current measurement: applying reference voltage of 0.75 times arrester 1mA DC ends (pulsating DC voltage portion is not greater than ±1.5%), current flows through arrester is not larger than predetermined value
1mA DC reference voltage: DC voltage is applied at both ends of surge arrester (pulsating DC voltage portion is not greater than ±1.5%), current flows through arrester stable at 1mA, value of read voltage is not less than predetermined value
Special note: gapless arrester allowed to work frequency discharge pressure test
