What is suspension clamp SO274?
The SO274 suspension clamp is one well-known model of suspension clamps, is a type of mechanical clamp for overhead cables used in overhead power transmission lines to support conductors. It is designed to secure the conductors to the supporting structure (such as a pole or tower) while allowing some flexibility and movement due to changes in temperature and tension. These clamps are typically used to suspend and stabilize the conductor, preventing excessive wear and mechanical stress.
Key features of suspension clamp SO274
-
Application: 4 core LV ABC service cables
-
Conductor range: 4×(25–50) mm²
-
Type: Wedge type, self locking, insulated dead end clamp
-
Installation: Tool free or shear head bolt design
-
Function: Anchor and tension cables at poles, corners, and endpoints
While European tension clamps are recognized for quality and standardized performance, Chinese manufacturers like Jera Line produce a robust range of LV cable termination tension clamps that can match or replace these clamps in many applications.
