How much temperature can high-temperature cables withstand?

The insulation layer of high-temperature resistant wires uses PFA Teflon, which can operate in environments of 180C and above for a long time. Generally, the working temperature is around 80C to 250 ℃, and can operate in environments of 300C for a short period of time. Polyoxyethylene propylene (F46) insulation shall not exceed 200C, and soluble polytetrafluoroethylene (PFA) insulation shall not exceed 260 ℃.

What should be paid attention to during transportation, loading and unloading of high-temperature wires and cables?

During transportation and loading and unloading, cables and cable trays should not be damaged. It is strictly prohibited to push the cable tray directly from the vehicle. Generally, cables should not be transported or stored flat. Before transporting or moving the cable reel, it is necessary to ensure that the cable reel is secure. The cable should be tightly wound, and the oil pipe between the oil filled cable and the pressure oil tank should be fixed without damage. The pressure oil tank should be secure, and the pressure indication should meet the requirements.

What are the fire prevention measures for high-temperature wires and cables?

Using flame-retardant cables. Use fire-resistant cable trays. Using fire-resistant coatings. Install fire barriers and fire barriers at cable tunnels, mezzanine exits, etc. Lightning protection cables should avoid oil pipelines and explosion-proof doors, otherwise local threading or insulation and fire prevention measures should be taken.

Which aspects should be considered when selecting the cross-section of high-temperature electric cables?

The following aspects should be considered: the working current that the cable is allowed to pass through for a long time. Thermal stability in case of short circuit. The voltage drop on the circuit should not exceed the allowable working range.

What are the advantages of high-temperature wires and cables compared to lightning protection wires?

Reliable operation, as installed in underground or other concealed areas, it is less susceptible to external damage and has less chance of failure. The power supply is safe and will not cause harm to people. Low maintenance workload and no need for frequent inspections. No need to install poles or towers. Helps improve power factor.
