Suspension Clamp for Polymer Insulators
Suspension clamps are used to connect conductors to insulators.
They are available in many types for different applications.
Some clamps include preformed rods, while others can be used with or without them.
There are also special slipping-type clamps that allow controlled movement of the conductor.
In simple terms, suspension clamps are parts used on an insulator string to support and hang conductors or ground wires on tower arms or substation structures.
Products Description
(1) Old-fashioned boat-shaped cable clamp
This kind of wire clip can be used for conductors and lightning protection wires. It can withstand the installation load of conductors within the vertical span, and does not allow the clamp to slide or break away from the insulator string when the line is running normally or is disconnected. The load-bearing pressure of the tower using this clamp is high.
(2) Pre-twisted suspension clamp
Function and its use: used for ADSS fiber optic cable, OPGW fiber optic cable, all kinds of wires and other wires in a straight line tower connection, the combination of inner and outer spiral pre-stranded wire can be very good protection of fiber optic cables, no concentration of stress, to avoid bending stresses, the cable to play a role in the protection and auxiliary vibration damping. The whole set of suspending wire clip includes: inner and outer pre-stranded wire, suspending head and matching connecting fittings. Clamp grip is greater than 10%-20% of the rated tensile strength of the fiber optic cable, easy to install.
The pendant cable clamps include hangers, U-shaped screws and hulls.
Regarding the maximum deflection angle, there is a certain limit for the pendant wire clamp. When the hull is turned to a certain angle, the U-screw will be blocked by the hanger. The maximum deflection angle is also a condition for safe operation. Maximum deflection angle and tower suspension point on both sides of the wire or ground hanging angle, but also with the diameter of the wire and ground (wire diameter should include wrapped aluminum tape thickness or guard line diameter), the larger the diameter of the U-shaped screws to move up, the maximum deflection angle is smaller. If greater than the maximum deflection angle should take measures, such as change double wire clamp, adjust the tower height, or special design of new wire clamps.
