NG-A (BTLY) isolated (flexible) mineral insulated cable
1. Uses This product can be laid in important places such as tunnels, cable trenches, bridges, trough boxes, shafts, high-rise buildings, rail transit, hospitals, shopping malls, exhibition halls, garages, entertainment venues, data centers and other important places.
2. Model and name Model: NG-A (BTLY) Rated voltage: 0.6/1KV Specification: 2.5-120mm2 (2-5 cores); 10-300mm2 (1 core) Single-core cable is recommended for conductor specifications above 120mm2 for convenience Laying.
3. Characteristic description BS6387 fire resistance ① Continuously energize for 180 minutes at 950°C without breakdown (C) ②Withstand 15 minutes of water spray after 15 minutes at 650°C without breakdown (W) ③Withstand 15 minutes of knock under 950°C flame Vibration without breakdown (Z) Advanced production technology, soft structure, sustainable production of NG-A (BTLY) isolated (flexible) mineral insulated cables. The continuous forming technology of metal sleeves used in the production process of NG-A (BTLY) isolated (flexible) mineral insulated cables enables the continuous length of the cable to satisfy customers Requirements, so as to achieve the whole root without joints, the whole section can be laid during the installation process and there is no need to wear pipes.
The design performance of NG-A series fire-resistant cables according to BS:6387 fire resistance requirements is as follows: continuous energization at 1.950℃ flame without breakdown for 180min; at 2.950℃ flame for 180min without immersion in water for 60min without breakdown; 3.950℃ flame withstand 180min of percussion vibration No breakdown; delivery of the entire NG-A series of fire-resistant cables without a connector The continuous forming process of the metal sleeve used in the production process of the NG-A series of fire-resistant cables allows the cable length to meet customer requirements, so that the entire cable can be delivered without a connector. During the installation process, the whole section can be laid and there is no need to wear pipes. Reliable insulation With mica tape insulation, the rated voltage of NG-A series fire-resistant cables can reach 0.6/1kV.
The application range of this product is expanded to 1kV power supply systems. The waterproof NG-A series fire-resistant cable adopts the continuous forming process of the metal sheath, which can achieve no joints in the middle, and eliminates the phenomenon of water in and out of the joints. Even if the BTL series mineral insulated cables are completely immersed in water, the seamless metal sheath can also be used. normal operation. Due to the existence of the continuous forming metal sheath, the rodent-proof NG-A series of fire-resistant cables effectively prevent the rodents and ants from damaging the cable. High mechanical strength NG-A series fire-resistant cables are fastened and durable. When designing the fire-resistant layer structure, we considered all possible impacts of fire conditions, so its fastening performance is better than that of steel tape armored cables.
