    How to distinguish between flame retardant and fire resistance of cables?

    17-08-2018

    Some electrical designers have unclear the concept of flame-retardant cables and fire-resistant cables, and do not understand the structure and characteristics of the two, resulting in the inability to properly design and select these two cables according to the power supply requirements, and design agents or supervision work on site. The installation of these two cables cannot be properly guided....

    There are main conductor DC resistance, insulation resistance, finished voltage test and insulated core voltage test. Each item is very important. The conductor resistance directly reflects the electrical transmission performance of the wire and cable, which directly affects the temperature and life of the wire and cable during power-on operation.voltage drop, and operational safety, it mainly exa...

    1. Power system The wire and cable products used in the power system mainly include overhead bare wires, bus bars (bus bars), power cables (plastic cables, oil-paper cables (substantially replaced by plastic power cables), rubber cables, overhead insulated cables), and branch cables. (Replaces some busbars), magnet wires, and electrical equipment, wires and cables for power equipment. 2. Informati...

  • What are the measures for cable fire prevention?

    What are the measures for cable fire prevention?

    20-07-2018

    Answer: (1) Use flame retardant cable; (2) using fireproof cable brackets; (3) using fireproof coatings; (4) Fireproof partition walls and fireproof baffles are installed at cable tunnels, mezzanine exits, etc.; (5) Overhead cables should be avoided from oil pipelines and explosion-proof doors. Otherwise, local pipe penetration or fire prevention measures should be taken.

    What is a flame retardant cable? What are the characteristics of flame retardant cables? The flame-retardant cable refers to the cable that is burned under the specified test conditions. After the test fire source is removed, the flame spreads only within the limited range, and the residual flame or residual burn can be self-extinguished within a limited time. Xiaobian analyzes the fundamental cha...
