Product classification
Pre-twisted suspension clamp
The pre-twisted protective wire has a simple structure and is wound on the outer layer of the wire. A set of pre-twisted wires form an empty tube to wrap the wire to prevent the wire from wearing out and reduce the stress and vibration of the wire.

Product Introduction
use:
It can be used to suspend conductors on poles and towers, not only can effectively protect the conductors, but also its smooth outer contour greatly reduces corona discharge. The high-performance aluminum alloy material has good energy-saving characteristics, so it is especially suitable for ultra-high voltage 220KV lines.
The double fulcrum suspension clamp can be used for long-distance transmission lines and large-angle pole towers across rivers.
structure:
1. Pre-twisted wire 2. Aluminum sheath 3. Aluminum U-shaped clip 4. Rubber gasket 5. Bolt assembly
Note: Parts 2, 3, 4, and 5 are set in the packaging bag, and each set is equipped with 1 set of pre-twisted wire
Features:
Optimal stress: The pre-twisted suspension clamp distributes the stress on the conductor on a larger area, greatly reducing the influence of static forces such as bending, shearing, and stretching on the conductor, and greatly improving the stress on the conductor Ability. Moreover, when the wire vibrates or even dances, it is not easy to cause damage to the overhang.
Lowest abrasion: The protective wire of the pre-twisted suspension clamp can hold the wire on both sides of the suspension point to withstand higher unbalanced loads, thereby avoiding wire slippage, and thus minimizing wire wear.
Excellent energy-saving characteristics: the unique design of the pre-twisted suspension clamp and high-performance aluminum alloy material can reduce electromagnetic loss and eliminate corona. The ball-shaped head or parrot beak end of the line protects the line to ensure that no tip discharge occurs. So as to achieve good energy-saving characteristics.
Anti-aging and loosening: The protective wire of the pre-twisted suspension clamp is made of material that matches the material of the wire, and at the same time has excellent elasticity and toughness. Compared with ordinary rigid aluminum protective wire, it has excellent performance. The anti-aging performance and anti-looseness of the product can be used safely for many years.
