(1) Overview
Low-voltage cable specification models are more in order to 1KV the following indoor PVC insulated PVC sheathed power cable terminals as an example shows the first cable production. (2) The construction process
Shake measuring grounding resistance → head → cut open the cable wrapped cable, electric cable terminal head → voltage cable core wire cable to connect the nose → apparatus and equipment (3) Major construction methods and technical measures
1) The shake test cable insulation
a. use 1KV shake shake table test on the cables, insulation resistance should be greater than 10MΩ.
b. Cable shake test has been completed, should be the core wire-to-ground discharges, respectively.
2) wrapped cable, electric cable termination caps
a. outsourcing stripped cable insulation, cable caps into the lower part of the first set of cables.
According to cable head model size, according to cable length and diameter of caps with a plastic tape wrapped semi-stacked cables. Should be closely wrapped plastic with the shape of Zaohe like.
c. put on the upper part of the cable caps, and the lower docking sets strict.
3) The core line-voltage cable wiring nose
a. From the end of the first Measure the length of the core line of the nose for the line depth, plus 5mm, cable core wire stripped of insulation, and the core coated with Vaseline line.
b. Insert the wire core wiring within the nose, with pressure wire wiring pressed his nose pliers, crimp pit should be two or more. Large-sized terminals should use hydraulic mechanical crimping.
c. Depending on the phase, the use of yellow, green, red, four-color plastic band of the core wire wrapped cable to the wiring crimping the nose area.
d. would do a good job the first cable end fixed at a pre-make the cable bracket on the head, and separated from the core wire.
e. According to terminals of the model, choice of bolt crimping cable terminals on the device, note should be made by a bolt-down or from the inside Waichuan, flat pad and spring should be installed and complete.
