Anti-flaming fireproof cable for electric welding machine

Abstract

The invention discloses an anti-flaming fireproof cable for an electric welding machine. A cable core comprises an S-shaped nylon framework, main conductors are arranged in semicircular arcs at the two ends of the S-shaped nylon framework respectively, each the main conductor is wrapped by a main cable core body formed by a TPE and an anti-flaming nylon composite insulation layer, and a power cable core body and a control cable core body are arranged on the two sides of the S-shaped nylon framework respectively; the cable core is sequentially wrapped by a taped covering, a shielding layer and a sheath layer. The S-shaped nylon framework is adopted in the anti-flaming fireproof cable, the mechanical properties of abrasion resistance, tear resistance and tensile strength of the cable are further improved, main cable cores and other cable cores are well distinguished, and therefore the application range of the cable is wide.

Description

technical field [0001] The invention mainly relates to the field of cables, in particular to a flame-retardant and fire-resistant cable for an electric welding machine. Background technique [0002] Existing electric welding machine cables include cable conductors, cable insulation layers, and sheath layers. The insulation and sheaths are made of rubber insulation and rubber sheath materials. The production of rubber insulation and sheaths requires rubber mixing first, and rubber extruders After extrusion, the vulcanized pipe needs to be vulcanized to ensure its proper mechanical properties, and in production, if the process parameters are not well controlled, problems such as under-sulfur, over-sulfur, and oxidized blackening of the conductor will occur. Influenced by it, the production cost of the cable is high and the production cycle is long. Therefore, the development of a new type of welding machine cable is completely in line with the needs of the market. Traditional...

[0002] Existing electric welding machine cables include cable conductors, cable insulation layers, and sheath layers. The insulation and sheaths are made of rubber insulation and rubber sheath materials. The production of rubber insulation and sheaths requires rubber mixing first, and rubber extruders After extrusion, the vulcanized pipe needs to be vulcanized to ensure its proper mechanical properties, and in production, if the process parameters are not well controlled, problems such as under-sulfur, over-sulfur, and oxidized blackening of the conductor will occur. Therefore, the development of new electric welding machine cables is completely in line with the needs of the market.

The traditional cable sheath material has the disadvantage of poor wear resistance, which leads to cable damage caused by friction between the cable product and the outside world during installation and use, thus affecting the protection and insulation performance of the cable.
