Description

Rubber sheath cable head water blocking device

technical field

The utility model relates to the technical field of rubber-sleeved cables, in particular to a water-blocking device for rubber-sheathed cable heads.

Background technique

Rubber-sheathed cable is a soft and movable cable variety with multi-strand thin copper wires as conductors, rubber insulation and rubber sheath. The rubber insulation and sheath production of rubber-sheathed cables generally adopts the saturated steam continuous vulcanization process. Steam continuous vulcanization is to make the core or cable of the newly extruded rubber insulation or sheath vulcanize in high-temperature steam through a continuous pressure steam pipe. The rear end of the vulcanized tube is cooled by a large amount of high-pressure water.

However, because there are gaps between the stranded conductors at the joint between the traction wire and the cable conductor or the cabled core, between the cabled cores, between the conductor and the insulating layer, between the cable core and the sheath, and the high pressure of the vulcanized steam , It is very easy to cause the cable to enter the cable during the vulcanization process, and the pressure steam penetrates into the cable from the gap and extends longitudinally, causing the cable to enter water. The water ingress of the cable seriously affects the quality, such as causing oxidation of the conductor, damage to the insulation or the sheath layer, and serious accidents will result. At present, cable manufacturers often cut off this section of cable to ensure the quality of the finished product, resulting in waste and increased cable production costs.

Therefore, how to solve the problem that high-pressure water vapor enters the interior of the cable during the vulcanization process of the rubber-sheathed cable is an urgent problem to be solved by those skilled in the art.
