Abstract

The invention discloses a high-strength fully-shielded crosslinked polyethylene insulated PVC sheath power cable, the power cable includes a skeleton, the skeleton is composed of seven skeletons withcross sections being orthohexagonal, wherein six orthohexagonal skeletons are distributed on six sides of the orthohexagonal skeleton in the middle, the seven orthohexagonal skeletons are in an integrated structure, a compression-resistant filling layer is filled inside the orthohexagonal skeleton in the middle, conductors are distributed inside the other six orthohexagonal skeletons, and an outerside of each conductor is wrapped by a polyethylene insulating layer and an aluminum plastic composite film shielding layer in sequence, and an outer side of the skeleton is wrapped by a zinc-coatedsteel wire braided shielding layer, a halogen-free glass fiber belting layer, a ceramic fiber thermal insulation braided layer and a PVC outer sheath in sequence. The skeleton braided with copper wires can play a role of compression resistance, can also increase the shielding performance of the cable, is not easy to damage in the use process and has a good thermal insulation effect.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a high-strength fully shielded cross-linked polyethylene insulated polyvinyl chloride sheathed power cable. Background technique [0002] Insulated PVC sheathed power cables are used in AC 50HZ, rated voltage (U0 / U) 0.6 / 1kv and below power lines for power transmission and distribution. Features: The maximum rated temperature of the cable conductor is 70°C. When short-circuited (the longest duration is not more than 5S), the maximum temperature of the cable conductor should not exceed 160°C; the ambient temperature when the cable is installed should not be lower than 0°C, and the minimum bending radius should not be less than 15 times the outer diameter of the cable. The conventional armored power cable structure is armored by wrapping double-layer steel tapes. During the cable construction, the cable is often damaged due to improper construction, which affects the use of the cabl...
