Description

Technical Field

[0001] The utility model relates to the technical field of wire harnesses, in particular to an explosion-proof wire harness. Background Art

[0002] Explosion-proof wiring harnesses refer to wires used in explosive, flammable and explosive dangerous environments. They are usually made of special designs and materials to prevent the wires themselves from generating sparks and causing explosions. They also have fire-proof and anti-static functions. Explosion-proof wires are widely used in industries such as petroleum, chemical and metallurgy.

[0003] The explosion-proof wiring harness structure is mainly composed of a wire core, an insulation layer and a protective layer. An explosion-proof wiring harness is generally used in combination with multiple wiring harnesses. When multiple wiring harnesses are combined, they are bundled with wiring harness straps to reduce the disorder of the wiring harnesses. The bundled wiring harnesses are densely packed, which makes the heat dissipation effect between the wiring harnesses poor. Heat accumulates between the wiring harnesses, which makes the wiring harness body easy to age, thereby reducing the service life of the wiring harness body. Therefore, we propose an explosion-proof wiring harness to address the above problems. Utility Model Content
