3 Terms and Definitions

The following terms and definitions apply to this document.

3.1

A composite material fastener for securing overhead insulated conductors (hereinafter referred to as "conductors") to insulators using bolt fastening.

Note. Use "BL" to represent it.

3.2

The method of fixing the conductor to the top groove of the insulator on the straight pole. Note. Represented by "D".

3.3 4 Structure, Classification and Labelling

The method of fixing the conductor to the side groove of the insulator on the straight pole. Note. Represented by "C".

4 Structure, Classification and Labelling

4.1 Structure

The rubber assembly consists of rubber parts with rubber cover and reinforcing liner, and fasteners.

4.2 Classification

According to the fixing location, it is divided into top groove fixing and side groove fixing, as shown in Figure 1.

a) Top groove fixing rubber assembly Figure 1 Schematic diagram of rubber component structure

b) Side groove fixing rubber assembly Index number explanation. 1 --- Rubber coating layer;

2 --- Insulator retaining ring reinforcing liner; 3 --- Fasteners;

4 --- Wire fixing ring reinforcing liner; 5 --- Wire retaining ring;

6 --- Insulator retaining ring;

phid1 --- Inner diameter of the insulator fixing ring;

phid2 --- Inner diameter of the conductor fixing ring;

h --- Height of the rubber component.
