Abstract

The invention belongs to the technical field of power cables and particularly relates to an intelligent and environment-friendly type power cable with aluminum alloy cores. The power cable facilitates detection and display of actual operating temperature of the power cable and facilitates computer remote contact and control. The power cable is composed of the three conductive wire cores, a computer contact and control unit line, a data transmission and temperature measurement line, a low-smoke, zero-halogen and high-flame-resistance lapping tape, a low-smoke, zero-halogen and high-flame-resistance extruded inner pad layer, a copper belt lapping shielding layer, a low-smoke, zero-halogen and high-flame-resistance extruded isolation sleeve, a single-layer aluminum alloy belt interlocking armor layer and a low-smoke, zero-halogen and high-flame-resistance extruded outer sheath. The power cable is structurally characterized in that the three conductive wire cores, the computer contact and control unit line and the data transmission and temperature measurement line are arranged on the inner side of the low-smoke, zero-halogen and high-flame-resistance lapping tape.

Description

technical field [0001] The invention belongs to the technical field of power cables, in particular to an aluminum alloy core intelligent environment-friendly power cable. Background technique [0002] In the construction of power system, long-distance transmission mainly depends on overhead cables, and the power transmission in the middle part is mainly completed by medium-voltage cables; therefore, medium-voltage power cables also have the characteristics of large transmission capacity and long transmission radius, which is also important for The safety level of medium-voltage power lines has higher requirements. Due to the lack of copper resources in our country and the relative abundance of aluminum resources, people naturally think of replacing copper with aluminum. However, in long-term practical applications, it is found that due to the low mechanical strength and poor flexibility of pure aluminum, during use Aluminum wires will crack and break during operation, and t...
