Description

Cable with interval changed by spacer and capable of improving protection capability

Technical Field

The invention relates to the technical field of aluminum alloy cables, in particular to a cable with a space changed by a spacer and improved protection capability.

Background

The aluminum alloy power cable is a novel material power cable which takes AA-eight-zero three-zero series aluminum alloy materials as conductors and adopts advanced technologies such as special roll forming molded line stranding production technology, annealing treatment and the like. The alloy power cable makes up the defects of the conventional pure aluminum cable, improves the bending property, creep resistance, corrosion resistance and the like greatly although the conductivity of the cable is not improved, can ensure that the cable keeps stable continuous performance when overloaded and overheated for a long time, adopts an AA-eight-zero three-zero series aluminum alloy conductor, can improve the conductivity and high temperature resistance of the aluminum alloy cable greatly, and solves the problems of pure aluminum conductor, creep deformation and the like. The conductivity of the aluminum alloy is sixty-one-eighth percent of the most common reference material copper IACS, and the current carrying capacity is seventy-nine percent of copper, which is better than the pure aluminum standard. But the actual weight of the aluminum alloy is about one-third that of copper in the same volume. Thus, the weight of an aluminum alloy cable is about half that of a copper cable at the same ampacity. The aluminum alloy cable is adopted to replace a copper cable, so that the weight of the cable can be reduced, the installation cost is reduced, the abrasion of equipment and the cable is reduced, the installation work is easier, and the spacing rods are hardware fittings which are arranged on the split conductors and used for fixing the spacing between the split conductors so as to prevent the conductors from mutually whipping and inhibit the breeze vibration and the sub-span vibration. The spacer is generally installed in the middle of the span, and the conventional spacer has the following disadvantages:

1. the traditional spacing rod is inconvenient to detect the temperature of the toilet surface of the cable, and the cost is not saved due to the strict spacing requirement due to single function;

2. the traditional spacer is inconvenient for detecting wind power and judging the distance according to the wind power grade, and the spacer is easy to break when the wind power is too large after the distance is fixed;
