What is ADSS Cable Fittings and Purpose?

2018/12/18

Tension Clamp:

ADSS Tension clamp pre-twisted wire is mainly used for aerial self-supporting ADSS fiber optic cable line is fixed, the anchor tight, generally installed in the terminal tower, tight lines Tension tower, corner tower and other locations.

Components:

Pre-twisted wire Each Clamp components include: internal wire cutter, wire cutter outside, pull the ring. Users can choose the configuration according to the design requirements of other connections.

Features:

Pre-twisted wire strain clamp on the wire (cable) and grip strength up wire (cable) ultimate tensile strength (RTS) 95%, and no stress concentration and vibration stress.

Single Clamp:

ADSS Single Clamp with Clamp similar to the role. Mainly used for short-span 50 to 200 meters corner, Tension, and terminal tower, not only for aerial fiber optic cable can be used for overhead wire, cable and other dock construction, installation and cable clamp for traction use.

Features:

Simple, quick and easy installation.

Composition:

Single Clamp is pre-twisted wire, pull rings, U-shaped ring and so on. Single Clamp can also be based on usage and user requirements by selecting aluminum-clad steel wire or galvanized steel wire material to manufacture.

Suspension clamps:

ADSS pre-twisted wire suspension clamps is mainly used for overhead self-supporting ADSS fiber optic cable lines, fiber optic cable for hanging purposes, and general suspension clamps similar to the role. Recommended angle ≤ 30 º in line when the environment.

Features:

1.Very low and reasonable distribution of static stress, improve the dynamic stress (such as vibration or dance) capacity, grip strength up to its ultimate tensile strength of fiber optic cable (RTS) of 10% to 20%.

2.No rigid contact with the fiber optic cable (Flexible Hold), so wear and tear to a minimum.

3.Excellent material to clamp a good flexibility and toughness, strong resistance to fatigue and corrosion protection, security, life long.

4.Not only effectively protect the cable, and its smooth contours and shape of the corona discharge electromagnetic loss greatly reduced.

Components:

Pre-twisted wire clamp from the inside twisted wire hanging outside the twisted wire, rubber plug, hanging plywood (shell) and so on. Users can choose the configuration according to the design requirements of other connections.

Dual suspension clamps:

ADSS pre-twisted wire pairs, also known as dual-pivot suspension clamp suspension clamps, which in addition to the general single-hanging clip of all performance, mainly used across rivers, valleys, etc. more than 800 meters long overhead ADSS fiber optic cable lines and corner 30 ° ~ 60 ° of the towers.

Features:

Cable fixed by the double-pivot support and protection to ensure the long span, large corner environment, safe and reliable operation of fiber optic cable.

Components: pre-twisted wire pairs of suspension clamps the inner wire, outer wire, rubber plug, hanging plywood, siding, panels and other components associated triangle. Users can choose the configuration according to the design requirements of other connections.

Mechanical suspension clamps:

Hanging clip is a short span of a drape clip, between the tangent and clamp suspension clamps between the pre-twisted wire. Applicable line span of 100 to 200 meters, the line angle of 15 º below the straight line tower. Gold with a breaking strength ≥ 40KN.

Features:

It has a tangential clamp convenient features, the addition of pre-twisted wire reinforced layer, and also enhanced resistance to fiber optic cable must be dynamic load capacity.

Components:

Strengthening layer by the mechanical suspension clamps pre-twisted wire, rubber plug, shell, U-shaped ring and so on.

Tangent clamp:

A straight line tangent clamp suspension clamps are kind of the main span of the overhead cable to provide small lightweight, simple, low-cost protection installation clamp, particularly for urban communication network construction and transformation. Mainly used for short-span 100 meters straight pole, or corner of the tower is less than 15 º on the fiber optic cable installation. Breaking strength ≥ 40KN.

Composition:

Each tangent clamp including: housing, rubber plug, bolts, nuts, washers, etc.

Pre-cut wire twisted cable clamp uses:

Pre-cut wire twisted cable clamp for 75 meters below the main line of the file straight from the tower.

Features:

Pre-cut wire twisted cable clamp and tangent clamp similar role, but the installation is more simple. Installers do not need special tools to hand operations can be successfully installed and is easy to ensure the quality of the installation, and also light weight.

Components:

Pre-cut wire twisted silk cord clamp folder by the pre-twisted legs, rings, rectangular hanging plates.

Anti-corona ring:

Mainly used in anti-corona ring and 220KV transmission lines over the same set of ADSS cable on the tower. As the pre-twisted wire cable and fittings are located in the high electric field space, the end of the pre-twisted wire with gold vulnerable to corona discharge effects. Of a threat to the safe operation of fiber optic cable. Anti-corona rings can greatly improve the state of pre-twisted wire end of the field, reduce the corona power generated by corrosion of the fiber optic cable to extend cable life.
