ADSS cable hardware price


拉线用预绞式耐张线夹 Preformed guy wire clamp

 

 

功能用途/ Function and Purpose

The clamp is mainly applied to fix the guy wires of the various types of poles or towers. It can replace the wedge clamp and U-T clamp used at present.

产品特点/ Product characteristic

²  Guy wire is finely protected because stress is equally distributed in large touching area without intensive stress pivot.

²  The grip is more than 95%RTS of guy wire.

²  The materials of clamp selected good quality materials to against corrosion.

²  Simple structure is convenient for installation. Manual operation on the spot without any requirement of the special tools.

²  Good resistance to vibration performance.

²  The revolving directions of the clamp shall be kept consistent. Generally, the standard dead-end clamp adopts right rotation. Please order in advance if you require left rotation.

使用须知/  Consideration

²  Select suitable dead-end clamp according to the guy wire specification.

²  The clamp can be used only once.

²  This product can be only operated by trained and skilled worker.

²  Be careful during working on live line or accessories to prevent electric shock.

 

应用实例/ Application


Introduction of aramid fiber for ADSS cable hardware accessories:
The full name of aramid fiber is "polyhydroquinone dimethylphenylenediamine" and its English name is aramid fiber (DuPont's trademark is Kevlar). In 1974, the United States Federal Trade Commission (FTC) named it "aramid fiber" and China named it aramid fiber. It is a new type of high-tech synthetic fiber, with super strength, high modulus, high temperature resistance, acid and alkali resistance, light weight and other excellent properties. It also has good insulation and anti-aging properties and long service life. Therefore, it is suitable for ADSS optical cable and ensures the service life of ADSS optical cable. It is defined that at least 85% of the amide chain (- CONH -) is directly connected with two benzene rings. According to this definition, a general-purpose polyamide polymer with main chain and ring chain fatty groups can be clearly separated from it. The features are as follows:


1. The radiation resistance of meta aramid fiber is very excellent.


2. Durability


Aramid fiber has good durability, which is reflected in all kinds of ADSS cable.


3. Excellent fire and heat resistance. Stable chemical properties


M-aramid fiber has excellent chemical resistance, high concentration of inorganic acid and good room temperature and alkali resistance.


5. Good mechanical properties


Meta aramid is a kind of flexible polymer with high breaking strength, large elongation, soft handle and good spinning property.


Use of aramid fiber:


Aramid fiber is not only an important cable material for ADSS cable fittings, but also an important material for developed national defense and military industry. At present, the United States, Britain and other national defense vest are made of aramid fiber, which effectively improves the military's combat capability. In addition, because of its light weight and strong strength, it can reduce good power materials, reduce the weight of spacecraft, improve flight speed, and reduce a lot of costs from the reality. Aramid fiber is widely used in high-tech fiber materials, such as: mechanical and electrical, construction, automobile, sporting goods and other aspects of the national economy.
