High-performance ultrathin dual-layer insulated conductor core capable of replacing single-layer insulated conductor core

Abstract

The invention discloses a high-performance ultrathin dual-layer insulated conductor core which is capable of replacing a single-layer insulated conductor core and structurally comprises a conductor, an inner insulating layer and an outer insulating layer, wherein the conductor is formed by regularly stranding a plurality of strands of fine copper wires with antioxidant films; by adopting a structure pressing technology, the conductor is smoother and more round; the inner insulating layer is made from material with excellent insulating property and mechanical toughness and a low smoke zero halogen irradiated and crosslinked network molecular structure; and the outer insulating layer is made from polyolefin material with excellent mechanical property and a low smoke zero halogen irradiated and crosslinked network molecular structure. After replacing the single-layer insulated conductor core, the ultrathin dual-layer insulated conductor core has the advantages of small outer diameter, light weight, irradiation resistance, high and low temperature (from minus 60-120 DEG C) resistance, oil resistance, halogen free, low smoke, low flammability, good mechanical performances (including high insulation tensile strength, high elongation at break and wear resistance), flexibility, high printing identification definition, good firmness and the like.

Description

technical field [0001] The invention relates to a high-performance ultra-thin double-layer insulated wire core instead of a single-layer insulated wire core. The insulated wire core has good electrical properties, mechanical properties, low-smoke, zero-halogen, and low-toxicity properties; it can replace the wires of traditional multi-core cables. The core is used in military or civilian industries such as various warships, river and sea ships and offshore oil platforms, transportation and industrial control panels. Especially used in special occasions that require low flammability, less smoke, low toxicity index, less corrosive gas, small size, and light weight. Background technique [0002] The traditional multi-core cable uses a single-layer insulated core. In order to take into account the electrical and mechanical properties of the single-layer insulation, even if the insulation is thin-walled, it cannot be made very thin (for example: the core used in the invention pat...
