Abstract

The invention provides an energy-saving pre-twisted spacer made of composite materials. The spacer comprises a spacer framework and a spacer supporting arm. A half-moon groove, a U-shaped groove and a pre-twisted thread armour rod passing through the half-moon groove and the U-shaped groove to fix a lead and the spacer supporting arm in a winding manner are arranged at the head of the spacer supporting arm. The U-shaped groove is internally provided with an anti-skidding rubber cushion. A circular empty slot is formed in the rear part of the spacer supporting arm. The circular empty slot is internally provided with a cross shaft sleeve and a rubber column. The rear part of the spacer supporting arm is connected to the end of the spacer framework. The energy-saving pre-twisted spacer made of the composite materials has the advantages of light weight, high mechanical strength, good stability, low energy consumption and the like. The spacer framework, the spacer supporting arm and the cross shaft sleeve are made of composite materials. The composite materials comprise non-magnetic polyamide engineering plastic and fiber enhanceosome, so that the energy-saving pre-twisted spacer made of the composite materials is excellent in anti-aging, high temperature resisting and wear-resisting performances and the like.

Description

technical field [0001] The invention relates to a spacer bar, in particular to a composite energy-saving pre-twisted spacer bar. Background technique [0002] Long-distance, large-capacity EHV / UHV transmission / transformation lines use two, four or more split conductors for each phase conductor. Split wire bundle spacing must remain constant to meet electrical performance and reduce surface potential gradients. Due to the vibration of the wires, electromagnetic force will be generated between the wire bundles, causing mutual attraction and collision, which will lead to electrical faults such as wire breakage, short circuit and even damage to the line tower. [0003] In order to avoid the above-mentioned accidents, spacers need to be installed at a certain distance in the power transmission / transformation line span, so that the distance between the split wire harnesses remains unchanged. The commonly used spacers are all made of metal, which is heavy and consumes a lot of...
