Copper and Aluminum Connector Fitting Bolt-type Parallel Groove Clamp for Conductor Connecting

The parallel groove clamp is used for connecting aluminum stranded wires with medium and small cross-sections, as well as steel core aluminum stranded wires, and steel-stranded wires for overhead lightning protection lines at locations without tension. It is also used for jumper connections on non-linear pylons. Electrical engineering materials (hardware) are used to connect conductors to each other, primarily in power line construction.

The reliability of line equipment is an important factor affecting power supply reliability, and among the various types of parallel groove clamps operating in urban and rural power grids in large numbers, their performance will directly impact reliable power supply. Low reliability of parallel groove clamps requires power supply companies to increase inspection frequency, shorten maintenance cycles, and increase operational costs. If parallel groove clamps cause faults or accidents, it can lead to widespread power outages and threaten the personal safety of urban and rural residents.

Parallel groove clamps are non-load bearing and mainly come in three types: bolt-type parallel groove clamps, H-type (or C-type) parallel groove clamps, and wedge-type parallel groove clamps, among which bolt-type parallel groove clamps are further divided into equal-diameter parallel groove clamps and unequal-diameter parallel groove clamps.
