1、 Introduction to Wire Spacer:
Spacer bars are commonly used for conductor and jumper wires. They are devices used to support and protect conductors and are typically used in overhead transmission lines. In transmission lines, wire spacers can prevent phenomena such as wire vibration, dancing, and wind swaying, while also improving the insulation performance and mechanical strength of the line, ensuring the safe and stable operation of the transmission line.
2、 Types and functions of wire spacers
1. Rigid spacer - a spacer that cannot produce relative displacement between sub conductors at the position of the spacer.
2. Damping spacer - a spacer with damping elements installed in the joint and clamp of the spacer, which can reduce the micro wind vibration and sub span oscillation of the split conductor.
3. Flexible spacer - a spacer that allows for an appropriate amount of relative displacement between sub conductors at the position of the spacer.
4. According to the structure of the split wire used for the spacer, it can be divided into two split, three split, four split, six split, eight split spacer and other models.
3、 Structural characteristics of wire spacers
Wire spacers are usually made of materials such as fiberglass, epoxy resin, aluminum alloy, etc., and have the characteristics of light weight, corrosion resistance, and easy installation. The shape and size of wire spacers may vary depending on different application scenarios and requirements.
4、 The naming meaning of spacers
Structural form of spacer: G-rigid spacer; R - flexible spacer; Z - Damping spacer frame shape:
Default represents a regular polygon; S - Cross shaped; J-rectangular; T-trapezoid; Y - Number of circular ring splits:
Use numbers to represent split spacing: Use numbers to represent, cm Applicable wire outer diameter:
Spacer anti dizziness performance: A - general grade; B - Intermediate level; C - Advanced; D - Special Grade
In short, wire jumper spacers are important transmission line protection devices that can effectively improve the safety and stability of transmission lines. With the continuous development of the power system, the technology and design of wire spacers are also constantly improving and perfecting.
