1.Description:
A. Connecting with pole tower by splicing fittings such as thimble , the outer stranded wires mainly bear line load.
B. As force transmission units, the inner stranded wires can partially protect adss cable, the main functions include:
(1)effectively deliver vertical pressing force to aramid fiber, the tension force bear unit of cable, as to protect cable sheath from damaging for overstress.
(2) deliver axial tension force.
(3) larger contact area with cable, even stress distribution, no stress concentration point.
C. In the premise of less than adss cable side pressure, it has some grip strength, can bear a certain amount of tension.
D.The guy grip strength for adss is 100% of cable ultimate tensile strength (uts), which completely accords with optical cable erection need.
E.To meet the needs of setting up adss cable in 10kv city network's distribution line, we produce tension clamp of 15kn grip strength, which has ad vantag
es of simple structure, easy installation and low cost.
Specifications:
Preformed guy grip is used in the installation of the exposed conductor also used in electric network transmission and distribution and overhead insulated conductor. The reliability and economic advantage is better than the present bolt type and hydraulic compression type tension set which now is being widely used in the line.The structure of the preformed tension set is simple , and the pipe structure formed by the two legs of the preformed line would enlace the conductor naturely and would produce a great holding strength. The novel structure and exact design all contribute to the reliability of the conductor tension set.The set is usually made of concentric-lay-stranded aluminium-clad steel conductors , galvanized iron wire strands and other materials.
Helical dead end clamps for opgw cable
1.Application and product description
Tension set for opgw is used to connect cable and tension pole or tower for opgw, and it's helpful to protect cable and reduce vibration.With special design of clamp, it will not produce stress concentration which damage opgw cable, and clamp grip strength is not less than 95% of the rated tensile strength, keep the cable properly.

Heart-shaped ring tension:
Hot galvanized steel precision, and failure load is 70kn, 100kn and 120kn.
Preformed armour rods:
Galvanized steel or aluminum clad steel wire, wall stick with emery, increase friction and reduce the pressure on the cable side, and was prefabricated into several sub-beams to prevent installation errors and to facilitate rapid installation.
Preformed tension rods:
Galvanized steel or aluminum clad steel wire, when pre-processing into a bunch, sticking with a solid diamond wall to reduce lateral pressure on the cable under the conditions of increased clamp grip. Tu preformed wire color-coded tags, to avoid installation errors, for quick installation.
Down lead clamp for tower
The down lead clamp is used in rivet the fiber when jumping or down lead , and it was commonly installed every 1.5 to 2 meter each set.
Vibration damper
Protective fittings
1, product fescription
In the way of high voltage overhead lines, close to the insulator on both sides of the wires are often a small hammer, the small hammer vibration hammer, is to reduce the wire for wind vibration and shame on. High voltage overhead line pole is higher, large span, when there is wind effect of conductor, vibration will happen. The wire vibration, wire hanging in the most unfavorable working conditions. Due to multiple vibration, wire for periodic bending fatigue damage will happen. When overhead line file from more than 120 meters, commonly used shock hammer shock.
T be directly installed on the opgw cables, installed with helical rods.
*calculate the installation distance, if it is within the helical rods, then installed as usual (installed on helical rods directly). If the installation position of vibration damper is outside of the helical rods, you should install helical rods. The distance between the end of the vibration damper and prot ection rods must be more than 70mm.
*the big damper weigh
t of low frequency is close to pole or tower.
*confirm the quantity per span length according to cable strength, span length and topography.

1,Product Description
Galvanized steel wire strand refers to any steel wire product which is subjected to a galvanizing process to improve its resistance to corrosion.
This process typically involves dipping the finished wire product into a bath of heated zinc compound to form a scratch and corrosion resistant coating across the entire surface of the wire.
2.Applications:
The galvanized steel wire strand is used for overhead ground lines or electrical power transmission lines. Stay wire or guy wire strands are produced for use with poles, towers, or any other form of guying.
Its low cost and ease of production makes galvanized steel wire ideal for mass produced corrosion resistant wire products,which is indispensable in industrial, agricultural.
Application
ADSS optical cable tangent clamp is mainly used in optical cable erecting within distance of 100MM
