NG-A is "mineral insulated fireproof cable". NG-A cable is a new generation of mineral insulated cable developed on the basis of BTTZ cable. In addition to the advantages of BTTZ cable, it also overcomes the problems and defects of BTTZ cable. It can overcome the defects of rigid fire-proof cables and give full play to the advantages of flexible fire-proof cables. Advantages, providing practical products for key projects.

NG-A is a mineral insulated fireproof cable that can overcome the shortcomings of rigid fireproof cables, give full play to the advantages of flexible fireproof cables, and provide practical products for key projects.
To put it bluntly, NG-A is a fire-resistant cable with BTLY copper sheath. The full name is NG-A (BTLY). Some users habitually write it as NG-A and BTLY.
NGA cable reliability.
1. To satisfy customers, the whole package can be supplied without joints.
2. The entire cable has no joints to prevent water from entering the cable.
3. The sheath is made of copper metal, which is chemically resistant and effectively prevents rodents from biting.
4. The use of inorganic materials ensures that the cable is durable, safe, reliable and has a long service life.
5. High production efficiency. The supply cycle of cables is generally about 7 working days. The production efficiency is high and the supply cycle is on time.
NG-A mineral insulated cable is widely used and has good water spray resistance in different occasions. It can work for a long time at an ambient temperature of 250℃ and can be used safely.
NG-A cable is a new generation of mineral insulated cable developed on the basis of BTTZ cable. In addition to having the advantages of BTTZ cable, it also overcomes the disadvantages of BTTZ cable. Problems and defects. And because the production length is not limited, there is no need for intermediate joints. It saves 10-15% in investment cost compared with BTTZ cable.
NG-A cable is made of inorganic materials and will not burn itself. At the same time, under the action of sheathed copper and magnesium oxide, NG-A cable can achieve a high degree of fire protection.
NG-A cable is a soft conductor structure that has been treated with special technology and has good electrical conductivity. Mechanical resistance properties. Flexible bending and high fire resistance; dense mineral material, resistant to high temperatures and fire; low smoke, low halogen plastic material with good anti-corrosion properties.
NGA fireproof cable advantages
1. Waterproof performance, good water resistance.
2. High mechanical strength and good resistance to mechanical impact.
3. Environmental protection characteristics overcome the ordinary PVC sheath material, which produces a small amount of water vapor when burned and is harmless to the environment.
4. Energy-saving characteristics and the same cross-sectional area can reduce the functional loss of the cable, and long-term use can reduce cost waste.
5. Easy to install, suitable for various laying methods, soft structure, easy to bend, no joints, convenient for electrical personnel to install and lay.
