The fire engineering involves a wide range of areas, such as fire protection, fire prevention and fire extinguishing, smoke prevention and control, etc. These are all related to our personal and property safety. Therefore, electrical engineering must be cautious when selecting construction wire and cable, for example, take fire protection engineering. In fact, the selected fire wire and cable must meet the continuous power supply time in the event of a fire, and ensure the integrity of the line and the normal operation of the system.
1. Selection of Non-Fire Electrical Circuits (1) Ordinary cables may be used for lay-out of ordinary equipment;
(2) Flame retardant wire and cable should be used for the laying of wires and cables; if it is used for secondary sites, the halogen-free low-smoke type should be adopted;
(3) Special-grade and first-class places Because it is a main power line with a particularly important load, the wire and cable should be halogen-free and low-smoke type.
(4) For timber-framed public buildings, mineral insulated cables should be used.
2. Selection of fire electrical circuits (1) Fire-retardant fire-resistant wires may be used if the fire-fighting equipment is used for a long time; flame-retardant wires may be used when the wires are applied in open or fire-retardant metal pipes in the refractory metal troughs. The power mains led to the fire fighting equipment by the substation (or the main distribution room) shall be flame-retardant fire-resistant cables or mineral insulated cables;
(2) It takes a long time to use electricity. Mineral insulated cable can be used for ≤1h distribution line surface coating. The thickness of the maintenance layer of the buried wall should not be less than 30mm.
(3) The use of electricity for a short time, <20min distribution lines wear metal pipes or closed metal trunking and coated with fire retardant coatings, can use ordinary wire and cable.
Jiaotai Cable Commitment Statement:
1. After leaving the factory, the cable product ensures compliance with the customer's regulatory requirements.
2. If the customer finds quality problems during use, JiaoTai cable staff will respond 24 hours after receiving the information and need to dispatch the relevant personnel within 24 hours after the site is resolved.
3. For those products that are truly the product quality issue of our company, we shall refund or replace or pack the service according to the customer's requirements. After the economic loss to the customer is confirmed, the compensation shall be paid in accordance with relevant regulations.
