Abstract

The invention discloses an electromagnetic heating ice-melting wire and a manufacturing method thereof. The electromagnetic heating ice-melting wire comprises an ice-melting core, an inner conductive layer and an ice-melting layer from inside to outside, wherein the ice-melting core is formed by twisting one or more aluminum-clad steel round wires; the inner conductive layer is formed by twisting heat-resistant aluminum alloy round wires; the ice-melting layer is formed by twisting special-shaped heat-resistant aluminum alloy wires and special-shaped aluminum-clad steel wires; and a first groove and a second groove are formed in the two sides of the top of the special-shaped aluminum-covered steel wire respectively. The ice melting speed is high, the tensile capacity is high, the sag performance is good, power transmission is not affected while ice melting is conducted, the problems of cable icing and power grid capacity expansion in the heavy ice area can be effectively solved, and the power transmission requirement of the heavy ice area can be met.

Description

technical field [0001] The technical field of the power transmission wire of the present invention, in particular, relates to an electromagnetic heating ice-melting wire and a manufacturing method thereof. Background technique [0002] my country has a vast territory, with many rivers, lakes, mountains and valleys, and the cross-regional meteorological environment is changeable. Strong winds, freezing rain, and icing can easily lead to faults such as deicing and jumping of conductors, short circuits between phases, and conductors colliding with lightning protection wires. In severe cases, it is easy to cause disconnection and tower collapse. These power outages seriously threaten the safety of people's property. Overhead transmission lines are faced with the test of various special environments and special terrains, and it is urgent to improve the safety of overhead conductors. [0003] In order to prevent the impact of extreme weather on power transmission lines, meet the p...
