To Description of 　　 mineral composite insulated aluminum sheathed protective isolation type flexible fireproof cable Mineral composite insulated aluminum sheathed protective isolation type flexible fireproof cable is a kind of high fireproof fire-resistant cable. It is filled or wrapped between the insulated core (outer diameter of the cable) and the sheath of the cable. Halogenated mineral composite materials or ceramic silicone rubber materials. When the cable is exposed to fire, the filling layer or the cladding layer will quickly crust. The crust is very hard and dense. It will not melt, drip, fall off, and cause no flame at 350-1600°C.

　　Instructions for mineral composite insulated aluminum sheathed protective isolation type flexible fireproof cable
Mineral composite insulated aluminum sheathed protective isolation type flexible fireproof cable is a kind of high fireproof fire-resistant cable. It is filled or wrapped between the insulated core (outer diameter of the cable) and the sheath of the cable. Halogenated mineral composite materials or ceramic silicone rubber materials.

2. Flame-retardant performance: the flame-retardant properties of fire-resistant cables comply with GB/T18380 flame-retardant class A

3, smoke-free and halogen-free : The halogen acid gas release test of the fire-resistant cable should be able to pass the standard requirements of GB/T17650.1, that is, the total amount of halogen acid gas is measured <5mg/g and GB/T17650.2 is used to measure the pH value and conductivity to determine the gas Acidity (PH≥ 4.3 conductivity in 1L water should not exceed 10US/mm), smoke density test should be able to pass the determination of the smoke density of GB/T17651.2 cable or optical cable burning under specific conditions (the minimum light transmittance≥60 %).
4. Withstand voltage: the fireproof cable should be able to withstand the 3.5KV AC voltage test without breakdown within 5 minutes
5. Waterproof: WDZAN-BTLY (NG-A) type fireproof cable adopts metal aluminum sheath for waterproof protection, so it is waterproof and has strong resistance to spray water.
6. Anti-mouse and ants: WDZAN-BTLY (NG-A) type fireproof cable is protected by a metal sheath, which effectively prevents the damage and damage to the cable by rats and ants.
7. High mechanical strength: WDZAN-BTLY (NG-A) type fireproof cable is sturdy and durable. When designing the fire-resistant layer structure, we considered all possible impacts under fire conditions, so its robustness is better than that of steel tape armored cables. span>

8, small line loss, Large current carrying capacity: For cables with the same cross-section, fire-resistant cables transmit higher currents than other types of cables. And can also withstand considerable overload. It is the smallest line loss among all flexible fireproof cables.
9. Corrosion resistance: It does not need to take additional protective measures; even in places where the metal sheath of the cable is prone to chemical corrosion or serious industrial pollution, because the outermost layer of the cable is protected by a plastic outer sheath, it is safe and sound.
10. Energy-saving and environmental protection: fire-proof cables are made of heat-insulating fire-proof materials. Therefore, in the event of a fire, the core operating temperature is lower than that of other types of cables. Therefore, the cable has low line loss during normal operation and saves energy consumption. It is especially suitable for applications in projects with environmental protection requirements.
11. Small bending radius: Due to the use of special aluminum and fireproof materials, the cable has a small bending radius and is easy to install. The single-core bending radius is 10D, and the multi-core bending radius is 15D (D is the outer diameter of the cable).
12. Metal sheath grounding: due to the continuity of the aluminum sheath and extremely low grounding resistance. It is recommended to be used as a ground wire.
