High temperature resistant heating cables

What should be paid attention to when the cable is transported and unloaded?

(1) During the transportation and loading and unloading process, the cables and cable reels should not be damaged. It is strictly forbidden to push down the cable reels directly from the vehicle.

(2) Before transporting or moving the cable reel, it is necessary to ensure that the cable reel is firm, the cable is tightly wound, the oil pipe between the oil-filled cable and the pressure tank should be fixed without damage, the pressure tank should be firm, and the pressure indication should meet the requirements.

What are the measures for cable fire protection?

(1) Use flame retardant cables;

(2) The use of fire-resistant cable brackets;

(3) The use of fire retardant coatings;

(4) Fire partition walls and fire baffles are set at cable tunnels, mezzanine exits, etc.;

(5) The discharge cable should avoid oil pipelines and explosion-proof doors, otherwise local pipe penetrations or thermal insulation and fire prevention measures should be taken.

Which aspects should be considered when choosing the cross section of the power cable?

The following aspects should be considered:

(1) The working current that the cable is allowed to pass through for a long time;

(2) Thermal stability in the event of a short circuit;

(3) The voltage drop on the line cannot exceed the permitted working range.
