Introduction of the difference between high temperature control cables and power cables

The power cable is the backbone of the power system to transmit and distribute large functional power. The rated voltage is generally 0.6/1KV and above. 

The high temperature control cable is used to directly transfer electrical energy to various power equipment and its rated voltage is 450/750V. 

This makes the insulation and sheath thickness of the power cable thicker than the high temperature control cable at the time of production. 

The differences are summarized as follows:

1. The high temperature control cable belongs to the cable for electrical equipment, and the power cable is two of the five major categories of cables.

2. The standards for high temperature control cables and power cables are different.

3. The color of the insulated core of the high temperature control cable is generally black printed white, and the low voltage of the power cable is generally color separation.

4. The cross section of the high temperature control cable generally does not exceed 10 square meters. The power cable is mainly for transmitting electricity and generally has a large cross section.


Features and uses of high temperature control cable: 

This product has high fire resistance. 

Under the direct combustion of flame, no short circuit or short circuit fault occurs within a certain period of time. 

Therefore, in the event of a fire, it is beneficial to reduce losses and low smoke. 

Halogen cable is an environmentally friendly cable that is mainly used in industries such as electric power, railways, large buildings, and ships with high fire protection requirements.

High-temperature control cable use characteristics:

1. AC rated voltage of high temperature control cable: U0/U 0.6/1KV.

2. Long-term working temperature: 

Flame retardant PVC insulation is 70 degrees Celsius and the sheath is 105 degrees Celsius.

Fluorine plastic insulation at 200 degrees Celsius and sheath at 260 degrees Celsius.

XLPE insulation at 90 degrees Celsius.

Low smoke halogen-free flame retardant polyolefin at 70 degrees Celsius.

Low-smoke, halogen-free, flame-retardant crosslinked polyolefin at 90 degrees Celsius and 120 degrees Celsius.

3. The ambient temperature flame retardant PVC sheath: Fixed laying -40 degrees Celsius, non-fixed laying -15 degrees Celsius.

Fluoroplastic insulation and sheath: Fixed laying -60 degrees Celsius.

Non-fixed laying -20 degrees Celsius.

4. The cable installation temperature is not lower than 0 degrees Celsius.

5. The recommended allowable bending radius for laying: The non-armored cable is not less than 6 times the outer diameter of the cable.

The armored cable is not less than 12 times the outer diameter of the cable.

The fluoroplastic insulated and sheathed cable is not less than 8 times the outer diameter of the cable.
