The composition and function of preformed suspension clamp

The suspension clamps of power line accessories are divided into old-fashioned boat-shaped clamps and preformed suspension clamps. What we are going to talk about today is the preformed suspension clamp, which is used as a connection accessory to hang the optical cable on the transmission line tower. The use of preformed suspension clamps can reduce the static stress of the optical cable at the suspension point, assist the damping of the optical cable, and restrain the dynamic stress of wind vibration; it can protect the optical cable.

1. Pre-twisted suspension clamps are used to connect ADSS optical cables, OPGW optical cables, various conductors, etc. In the straight tower, its composition is as follows:

2. Composed of aluminum splint components: The aluminum splint for pre-twist suspension fixtures has corrosion resistance, stable chemical properties, good resistance to atmospheric corrosion, and good mechanical properties.

3. Hot-dip galvanized parts for power accessories: bolts, spring washers, flat washers, nuts, etc.

4. The helical suspension clamp adopts rubber clamp components: ozone resistance, chemical resistance, weathering resistance, high and low temperature performance, high strength and elasticity, and small compression deformation.

5. Pre-stranded wire: aluminum alloy wire made according to predetermined mechanical properties and chemical composition. High tensile strength, hardness, good elasticity, strong anti-rust ability, long-term use in harsh weather.

6. Closed pin: power standard parts.

7. Outer pre-twisted wire: the same as the pre-twisted protective wire.

8. Power connection fittings: U-shaped lifting ring, U-shaped screw, UB-shaped hanging plate, ZH-shaped lifting ring.
