Abstract

The invention relates to a novel method for vulcanizing rubber-insulated electric wires and cables, belonging to vulcanizing method of rubber-insulated electric wires and cables. The method comprises the following steps: injecting nitrogen gas with the pressure of 0.5-0.7MPa into a vulcanized conduit or a container; carrying out galvanothermy radiating heating on the electric wires and cables through the vulcanized conduit or the container, and the galvanothermy radiating temperature is 240 DEG C-400 DEGC. The invention has the advantages of lowering the pressure level of the vulcanized system and more easily realizing encapsulation of nitrogen gas. The max temperature of galvanothermy radiation can reach 400 DEG C so as to facilitate the application of high-temperature rapid vulcanized system and intelligent advance equipment to be possible. The vulcanized cable has smooth surface resulting from that vulcanizing medium environment is dry without moisture. The invention has the advantages of saving investment, avoiding pollution to the air and the environment by the coal burning boiler, thus having bright popularization prospect.

Description

technical field [0001] The invention belongs to a method for vulcanizing rubber insulated wires and cables. Background technique [0002] The traditional vulcanization process of rubber insulated wire and cable includes continuous vulcanization and tank vulcanization. The tank vulcanization is to put the unvulcanized rubber insulated wire and cable together with the cable reel into the vulcanization tank, close the tank door and pass it into the supersaturated vulcanization tank. Combine steam to make the cable complete the vulcanization process under the steam pressure and temperature of 1.6-2MPa. During this vulcanization process, the cables in the inner layer of the cable reel will be deformed to a certain extent under the pressure and temperature of the outer cable, which will affect the cable. The roundness and appearance quality, so it is only suitable for small conductor cross-section, low voltage level wire and cable. The whole production process of the continuous v...
