A processing technology for cross-linked polyethylene insulated fire-resistant and flame-retardant power cable

Abstract

The present invention discloses a processing technology for a cross-linked polyethylene insulated fire-resistant and flame-retardant power cable, which relates to the field of cable technology and includes a plurality of copper conductors, wherein a fire-resistant layer and an insulating layer are sequentially arranged on the outside of the copper conductors, and the plurality of insulating layers are coated with a tape. The present invention drives the horizontal movable plates on both sides to move horizontally at equal distances through the inclined groove and the pin shaft during the rising process of the lifting plate, thereby driving the traction plates 1 on both sides to open at equal distances; and by adapting the trapezoidal block 1 to the trapezoidal block 2 in the groove, the movable plate can be pushed to move outward, stretching the spring, thereby driving the guide wheel 1 out, and multiple guide wheels can be added to pull the copper wire, which is more practical. When not in use, the guide wheel 1 automatically returns to the traction plate 1, saving space; and multiple traction plates 2 can be connected to the traction plate 1, which can pull multiple copper wires and reduce costs.
