Abstract

The invention discloses a drawing head of a high pressure cross linking cable, which belongs to the field of electric wires, and consists of a draw bar, a guiding cone, a steel sheath, a fastening screw, a waterproof adhesive tape and a thermal shrinkable sleeve; the draw bar is welded on a conductor; the guiding cone is sheathed on the draw bar; the steel sleeve is fixed on a cable body through a screw; the draw bar is welded on the steel sleeve; lead welding is adopted for the steel sleeve and a cable metal sleeve; the waterproof adhesive tape is arranged and wounded on the connection between the steel sleeve and the cable metal sleeve; the thermal shrinkable sleeve is arranged on the steel sleeve. The drawing head of a high pressure cross linking cable drawing head of a high pressure cross linking cable has simple structure, convenient connection, reliable mechanic intensity and waterproof sealing property; jamming of the cable when passing through a pipe is solved, thus is convenient for construction.

Description

technical field [0001] The high-voltage cross-linked cable pulling head of the invention belongs to the field of electric wires and cables. Background technique [0002] The main purpose of the cable puller is to facilitate cable laying and protect the cable from water ingress during construction. Therefore, the puller should have sufficient mechanical strength and reliable waterproof sealing performance. In the construction of cable laying, it needs to bear a large traction force and side pressure, which can easily cause cracks and damage, which will cause accidents such as falling off of the traction head and water seepage of the cable. Can not be put into use, causing great loss. Contents of the invention [0003] The purpose of the present invention is to avoid the deficiencies in the prior art, and provide a high-voltage cross-linked cable pulling head with improved mechanical performance and waterproof sealing performance of the pulling head. [0004] The object of...
