(1) electrical insulation. Maintaining the insulation of power distribution lines and electrical equipment is the most essential factor to ensure the normal operation of personal safety and electrical equipment. Electrical insulation. It can be measured by measuring its insulation resistance, compressive strength, leakage current and dielectric loss.

(2) safe distance. Electrical safety distance refers to the safe and reliable distance of the body, body and other close to charged body without danger. If the charged body is between the earth and the ground. Between the body and the charged body, between the charged body and the body, between the charged body and other facilities and equipment, the distance should be maintained.


(3) safe carrying capacity. The safe carrying capacity of a conductor is the allowable continuous flow of electricity through the conductor. If the current through the conductor exceeds the safe carrying capacity, The heat of the conductor will exceed the allowable value, leading to insulation damage and even leakage and fire. Therefore, the conductor section and selection are determined according to the safe load flow of the conductor.

Preparation is very important.

(4) logo. Obvious, accurate and uniform signs are important factors to ensure the safety of electricity. The logo usually has color mark, sign mark and model mark, etc. color. A conductor indicating different properties and USES; Signs are generally used as signs of dangerous places; The model mark is the symbol of the special structure of the equipment.
