H0FR Cable

Cable Structure:

Conductor Material: Tin-plated copper/standard copper, Category 6 as per BS6360 standard, with Category 5 conductors for 120 mm2 and above.

Isolation Strip: Crepe Paper/Polyester Tape

Insulating Materials: Acid and alkali-resistant blend, Ethylene Propylene Rubber (E.P.R.) insulation

Housing Material: Acid and alkali-resistant blend, Chloroprene (C.S.P.) (heat-resistant and flame-retardant)

Sheath Color: Black, Grey, Yellow (Tinned Copper Conductor), Black (Standard Copper Conductor)

The structure above can be used to create soft aluminum conductors.

Application:

These cables are designed for high flexibility and are primarily used for secondary connections of automatic or hand-held arc welder electrodes. They can also be used in non-welding equipment, such as grounding circuit conductors, flexible trailing cables for power transmission, and busbar connection devices.

Technical Specifications:

Rated Voltage: 100V (in environments where mechanical damage is not tolerable); such cables can operate at 450/700V in control panels and switchgear.

Rated Temperature: -20 to +85°C

Bend Radius: 6 times cable diameter

Rated Parameters:

Here are the rated current values based on an ambient temperature of 25°C; the corresponding rated factors at higher temperatures (as a ratio to the values at 25°C) are as follows:

If the total length of cable to be installed exceeds 15 meters, it is necessary to choose a cable with a larger cross-sectional area to ensure that the voltage drop is not excessive, thereby maintaining a sufficiently high welding current level.

Cycle Value:

The cycle value size represents the percentage of the entire cycle (5 minutes). The duration of time in a welding operation is continuously changing. Therefore, the cycle value varies between 20% (interrupted or occasional positioning welding) to 100% (automatic welding).

Automated positioning welding up to 100 %.

Semi-automatic positioning welding 30-85%.

Manual positioning welding 30-60%.

Intermittent or occasional positioning welding up to 20%.

Correction Factor

Due to the influence of ambient temperature, the working temperature of the cables also varies. These cables are designed to operate stably at ambient temperatures ranging from 25 degrees Celsius to 85 degrees Celsius. The correction factors for higher ambient temperatures are as follows:

Conductor Impedance (ohms/km) and Voltage Drop
