Purpose and Structure

Preformed armor rod used to protect conductor against vibration, wire clip compressive stress, friction, arc and all other outside damage. When the vibration is not serious, short preformed armor rod can protect conductor against arc, rub or other damage in short span of line. It is used to repair the damaged conductor as the repair wire. It restores original mechanical strength and electrical conductivity, and also can use to protect branch line, make wire branch point avoid damage from arc and friction.

Preformed armor rod and short preformed armor rod have the simple structure, a group stranded wire form throughway pipe, and bundle produce by the clenched force, thus protecting wires.

Characteristics

1) Low wear: Due to the substantial bar and short substantial clench conductor, the wire is hard to slip, the wear will be minimum.

2) Prevent loosening: The preformed has holding elasticity, it ensure it not loose in long time;

3) Good corrosion-resistance Characteristics: After antirust processing, the wire ensuring the strong corrosion resistance;

4) Easy Installation: no special tools, the hand can install quick and easy in locale, one person can ?nish;

5) Installation quality assurance: No need the special training; it can be inspected by naked eye. The appearance is concise and beautiful.

6) Good commonality: match with various hardware.

Jointing explanation

1. When the outermost aluminum wire of ACSR Conductor and the outermost Al wire of Al conductor have less than 25% line happen breakage, it can be repaired by short performed armor rod, the conductor restore 100% of the machinery and electrical properties.

2. When the outermost aluminum wire of ACSR Conductor and the outermost Al wire of Al conductor have 25%-50%line happen breakage, it can be repaired by short performed armor rod, the conductor restore 100% of the machinery and electrical properties.
