What Are The Classification And Performance Of Commonly Used Electrical Fittings

According to their functions and structures, power fittings can be divided into categories such as suspension wire clamps, tension wire clamps, connecting fittings, Two Pole Distribution Blocks, protective fittings, equipment wire clamps, T-type wire clamps, busbar fittings, and wire pulling fittings.

Connecting fittings are mainly used in overhead power lines or substations to connect conductors, lightning arrester clamps to insulators or insulators, lightning arrester clamps to pole towers. According to different installation conditions, special connecting fittings refer to ball head hanging rings and bowl head hanging plates connected to insulators. General connecting fittings are suitable for various situations and are graded according to load tonnage. Fittings with the same load are interchangeable.

Splicing fittings are mainly used for overhead power line conductors, lightning arrester splicing and repair. According to different structural forms and installation methods, they are divided into three types: compression type, bolt type and pre-twisted wire type: compression type is further divided into three types: hydraulic, explosive pressure and clamp pressure.

Power fittings are metal accessories that connect and combine various devices in the power system and play a protective role.

The samples of power fittings are reasonably designed and have excellent performance, which can meet the construction needs of ultra-high voltage AC transmission line projects.
