0361TQ HOFR Black Welding Cable

What is 0361TQ BS 638 Black Welding Cable?

The 0361TQ BS 638 Black Welding Cable is a specialized, extra-flexible single-conductor industrial welding cable manufactured in accordance with BS 638 Part 4 and EN 60228. It is purpose-built to deliver high-amperage electrical current from welding generator sets and transformer rectifiers directly to electrodes, earth clamps, and welding guns.

Engineered to withstand arduous handling on factory floors and outdoor construction sites, the cable features an oil-resistant, flame-retardant (HOFR) rubber outer covering bonded over an EPR dielectric core. Its finely stranded pure copper construction ensures low fatigue under repeated bending and dragging across rough surfaces, while the HOFR elastomer compound protects the assembly against hot slag, spatters, and industrial grease in compliance with IEC/EN 60332-1-2 flame propagation standards.

0361TQ BS 638 Black Welding Cable Construction

• Conductor: High-conductivity annealed plain copper; Class 6 extra-flexible stranding for sizes 16mm² to 95mm², and Class 5 flexible stranding for sizes 120mm² and above per EN 60228 (also available with aluminium conductors on request).
• Separator: Synthetic Polyester Tape (PET) applied helically over the conductor to preserve flexibility and facilitate clean stripping.
• Insulation: Ethylene Propylene Rubber (EPR) delivering thermal endurance and dielectric strength.
• Outer Sheath: Heavy-duty HOFR (Heat and Oil Resistant and Flame Retardant) elastomeric rubber compound.
• Sheath Colour: Industrial Black.

Applications

0361TQ BS 638 welding cables are engineered for high-current power transmission across severe mechanical and thermal working conditions:

• Manual & Automatic Arc Welding: High-current leads for manual metal arc (MMA), MIG, TIG, and automated submerged arc welding systems.
• Automotive & Conveyor Assembly Lines: Flexible secondary jumper cables on spot-welding robots and multi-point automated production lines.
• Shipbuilding & Marine Fabrication: Heavy-duty, oil-resistant portable ground and electrode leads in dry docks and shipyards.
• Auxiliary Power Circuits: Temporary power feeds up to 450V when suitably protected against mechanical damage.

Specifications & Dimensions

Huadong Cable Group manufactures 0361TQ BS 638 black welding cables across nominal cross-sectional areas from 16mm² up to 240mm². Operating at a rated welding voltage of 100V across a flexing temperature range of -20°C to +85°C, the series features total covering radial thicknesses ranging from 2.0mm to 3.4mm, nominal overall outer diameters from 9.7mm (16mm²) up to 27.8mm (240mm²), and nominal unit weights spanning 215 kg/km to 2,534 kg/km. Maximum conductor DC resistance values at 20°C strictly conform to EN 60228 (1.21 Ω/km for 16mm² down to 0.0817 Ω/km for 240mm²). The cable accommodates single-cycle 5-minute operation current ratings up to 780A at 100% duty cycle and up to 1,250A at 35% duty cycle for 240mm² conductors, while maintaining a compact flexing minimum bending radius of 6 times the overall diameter in strict accordance with BS 638 Part 4 guidelines.

Frequently Asked Questions

Q: What is the significance of the HOFR rating on 0361TQ welding cables?
A: HOFR stands for Heat and Oil Resistant and Flame Retardant; this compound ensures the outer rubber jacket does not soften or degrade when exposed to hot welding spatter, lubricating oils, or industrial fuels.

Q: How does the duty cycle affect the current carrying capacity of this cable?
A: Current carrying capacity increases as the duty cycle decreases within a 5-minute operational cycle; for example, a 70mm² cable carries 355A at a continuous 100% duty cycle, but can safely handle up to 600A at a 35% duty cycle.

Q: Can 0361TQ cable be used for applications other than electric welding?
A: Yes, it is permitted for auxiliary power connections at voltages up to 450V, provided that the cable is adequately protected from mechanical abuse and physical crushing.

Q: What commercial payment terms does Huadong Cable accept for international orders?
A: We accept standard international commercial payment terms, primarily Telegraphic Transfer (T/T, with 30% advance deposit and 70% against shipping documents) and 100% Irrevocable Letter of Credit (L/C) at sight.
