What is pre-twisted wire? How to repair pre-twisted wire?
The pre-twisted wire is used for the connection fittings of overhead power conductor and power overhead optical cable terminal, suspension, joint, etc. Pre-twisted wire appeared in the United States as early as the 1940 s and 1950 s. The initial products were spiral protective lines for the protection of bare wire stress concentration positions and electric corrosion and arc burning positions. After years of development, pre-twisted wire fittings have been widely used in power transmission and distribution, optical fiber communications, electrified railways, cable television, construction, agriculture and other fields.
