Embodiment 1
[0022] A kind of preparation method of rubber cable joint is as follows:
[0023] (1) Making the inner semiconductive layer of the rubber cable joint:
[0024] Remelt the semi-conductive mixed rubber into a 6mm thick film, cut it according to the sample, prepare the material weight 100 grams per piece, and produce 4-6 pieces for each set of molds; put the prepared rubber material into the mold of the inner semi-conductive layer, Push the mold into the rubber flat vulcanizing machine, close the mold and pressurize it, deflate it at least twice, and vulcanize it for 600 seconds at a temperature of 168°C and a pressure of 18MP;
[0025] (2) Making the outer semiconductive layer of the rubber cable joint:
[0026] Remelt the semi-conductive mixed rubber into a film with a thickness of 4mm, cut it according to the model, prepare the material weight of 240 grams per piece, and produce 2 pieces for each set of molds; put the prepared rubber material into the mold of the outer semi-c...
