10KV高压电缆头冷缩（国外英文资料） 10KV high voltage cable head cooling process The environmental requirements of production The production of the head of a 10kV cable cooling terminal must be in a clear, dry air The construction site should be cleaned without flying dust or scraps of paper. The requirement of cable in production The 10kV cable should be clean and unbreakable, with insulation resistance and dc resistance The test is carried out after the test is qualified. The sealing of the cable head shall be sealed Closure.  Three step (1) stripping, steel and lining. Straighten the cable, clean and strip away from the installation Put the outer sheath of the terminal, the steel armor and the 30mm, the inner sheath 10mm, and use the wire or the P The VC band is wound round steel to prevent loose. Copper shield ends with PVC tape in case of loose copper To shield the folds of the fold from the PVC tape, to prevent the damage of the cooling tube.  (2) fixed steel armor line. Push the tripod cones into the cable bifurcation and light steel armor The paint and rust of the steel wire are fixed to the steel armor by the large constant-force spring. In order to firmly, The ground line should leave 10 ~ 20mm head, the constant force spring takes it around a circle, turn the head of dew back Im going to do it with the constant force spring. So does the fixed copper shield.  (3) wrapping the glue. From the following 50mm to the full force spring, steel armor and inner armor, Wrap the two layers of glue with the filling glue, and a layer at the side of the fork Full.  (4) fixed copper shielding ground. Divide one end into three strands and use three small constant forces The spring is fastened to the three-phase copper shield, and then the spring is pushed as far as possible. Wire the steel wire Keep the copper shield separate, not short. (5) sticky tape. A layer of black self-adhesive tape for the filling and small constant force spring It is easy to pull out the plastic bar in the c
