Product Description
Suspension Clamps are used as a component of insulator string which we can use it to hang conductor or ground wire to the tower arms or substation structures with insulators and line fittings.
Power fittings suspension clamps are divided into old-fashioned boat-shaped clamps and pre-twisted suspension clamps.
Pre-twisted suspension clamps:
Pre-twisted suspension clamp functions and uses: used for connecting ADSS optical cables, OPGW optical cables, various conductors, etc. in linear pole towers. The single-sided suspension angle is 15°-18°. The combination of inner and outer spiral pre-twisted wires can be very A well-protected optical cable has no concentrated stress, avoids bending stress, and plays a role in protecting the optical cable and auxiliary vibration reduction. The complete set of suspension clamps includes: inner and outer pre-twisted wires, suspension heads and supporting connecting hardware. The clamp's holding force is 10%-20% greater than the rated tensile strength of the optical cable, making installation easy.
Inner twisted wire, outer twisted wire, suspension head and rubber block, U-shaped ring, aluminum sleeve, bolts, nuts, closing pins and other supporting connecting hardware.
Interpretation of the function of pre-twisted suspension clamps:
Pre-twisted suspension clamps are used to connect various conductors such as ADSS optical cables and OPGW optical cables in linear pole towers. The use of pre-twisted suspension clamps can protect optical cables well and have auxiliary reduction effects. The vibration effect greatly extends the service life of the line.
The combination of inner and outer spiral pre-twisted wires protects the optical cable. It can make the stress of the conductor evenly distributed without concentration points.
It can enhance the stiffness of the cable installation point and has good protection performance for the optical cable.
The cable clamp has strong grip, which can reach 10%-20% of the rated tensile strength of the optical cable, and has strong dynamic stress tolerance.
The combination of inner and outer spiral pre-twisted wires allows the clamp to have a larger contact area with the optical cable, and is equipped with a flexible rubber clamp block to enhance self-damping and reduce wear.
It has the function of anti-corona ring. The anti-corona ring can greatly improve the electric field state at the end of high-altitude optical cables and pre-twisted wires, reduce power loss, reduce the electrical corrosion of optical cables due to corona, thereby extending the service life of optical cables.
The use of high-quality aluminum alloy materials improves the mechanical properties and corrosion resistance of the clamp, greatly extending its life.
The installation is simple. Construction workers do not need to prepare special tools and can successfully complete the installation with bare hands. It is easy to ensure the installation quality. It is also lightweight, maintenance-free and reduces construction costs.
Advantage:
The use of pre-twisted suspension clamps can reduce the static stress of the optical cable at the suspension point, assist in the shock absorption of the optical cable, suppress the dynamic stress of wind vibration, and play a protective role in the optical cable.
Pre-twisted suspension clamps are divided into Suspension clamp for OPGW and Suspension clamp for ADSS:

Product Features:
a. The suspension clamp has a large contact area with the ADSS optical cable, the stress is distributed evenly, and there are no stress concentration points. At the same time, it increases the stiffness of the hanging point optical cable and plays a better protective role.
b. It has good dynamic stress tolerance and can provide sufficient gripping force to protect the ADSS optical cable when operating under unbalanced load conditions.
c. The structure is equipped with soft rubber clamps to achieve self-damping and reduce wear.
d. Use aluminum alloy protective strips to protect optical cables.
e. The ends are rounded to increase the corona initiation voltage.
f. The aluminum alloy material improves the mechanical performance and anti-corrosion performance of the cable clamp, greatly extending the service life.

Product Use:
This kind of pre-twisted suspension clamp is a connecting fitting for suspending OPGW optical cables on transmission line towers. The cable clamp can reduce the static stress of the optical cable at the suspension point, improve the vibration resistance of the optical cable, and suppress the dynamic stress of wind vibration; it can also ensure that the bending of the optical cable does not exceed the allowable value, so that the optical cable does not produce bending stress. Since the cable clamp is installed on the optical cable, no harmful stress concentration will occur, so the optical fiber in the optical cable will not produce additional losses.
Product Structure and materials:
This product is a combination wire clamp, equipped with a hanging head (each hanging head is composed of a rubber clamp, an aluminum splint, a bolt, a spring washer, a flat washer, a nut, a closing pin, etc.), an outer layer of pre-twisted wire, and a protective wire pre-twisted wire. etc. are combined.
The pre-twisted wire of the protective strip is directly wrapped around the surface of the optical cable to provide protection and stiffness for the optical cable. The pre-twisted wire of the protective strip is clamped by the rubber clamp insert, and the middle lay length of the outer pre-twisted wire presses the drum-shaped rubber clamp. , and then clamp the outside with aluminum plywood.
Aluminum plywood ------ is made of corrosion-resistant aluminum alloy pressure casting. The aluminum alloy has stable chemical properties, good atmospheric corrosion resistance, and good mechanical properties.
Rubber clamp------composed of high-quality rubber and central reinforcement, it has ozone resistance, chemical resistance, weather aging resistance, high and low temperature performance, high strength and elasticity, and small compression deformation.
Bolts, spring washers, flat washers, nuts ------ hot-dip galvanized standard parts.
Closing pin------electrical standard parts.
Protective wire pre-twisted wire------aluminum alloy wire customized according to predetermined mechanical properties and chemical composition. It has high tensile strength, hardness, good elasticity and strong anti-rust ability, and can survive in harsh climates. environment for long-term use.
The outer layer of pre-twisted wire is the same as the protective wire pre-twisted wire.
Connection hardware ------ U-shaped hanging rings, U-shaped screws, UB-shaped hanging plates, and ZH-shaped hanging rings are all standard electrical parts.
