1.Products Structure

1) The conductor is copper core extruded round stranded conductor

2) The insulating layer is pure gold mica tape (not combined with the extruded insulation material, thereby eliminating the generation of carbon particles and improving the electrical stability)

3) Metal sheathed aluminum or aluminum alloy isolation layer (not for grounding)

4) Isolation sleeve (cross-linked insulation)

5) Refractory layer (inorganic aluminum hydroxide AL(OH)3 or Mg(OH)2) which is non-combustible and infusible under flame

6) Outer sheath clinker (polyolefin or polyethylene)

2.Product Characteristics

1) The fire resistance standard can pass the British BS6387 three evaluations: 950 °C 3h flame without breakdown, 650 °C 30min after 15min water spray (direct water can also be), 950 °C flame under 15min percussion vibration Without damage, the BTTZ assessment standard is fully achieved in terms of fire resistance.

2) The product can produce 1-37 cores in 1.5-6 square meters, 1-5 cores in 10-240 square meters, and single cores in 300-630 square meters. NGA (BTLY) mineral insulation flexible (isolated) cable production process used in the metal sheath continuous molding process, so that the cable length can meet customer requirements, so that the entire jointless whole delivery.

3) The whole process can be laid during the installation process and there is no need to wear the pipe. It has the same waterproof and anti-shock function of BTTZ.

4) It has good anti-mouse, anti-ant and anti-radiation functions to ensure the stability of the cable, long life and durability.

5) NGA (BTLY) mineral insulated flexible (isolated) cable cores have lower operating temperatures than other types of cables, so the mineral insulated cables have low line loss during normal operation, saving energy consumption in projects with environmental requirements. Especially suitable for applications. The radiation of inorganic materials used in a large number of cables can ensure the stability of the cable, long life and durability, and can be used in nuclear power and other fields.

6) Explosion proof. (The highly compacted insulation material in the cable and the cable terminations installed in the special gland can prevent steam, gas and flame from entering the electrical equipment connected to the cable, thus connecting the explosion hazard and various explosion-proof equipment and equipment.)

7) NGA (BTLY) mineral insulated flexible (isolated) cable metal sheath has high corrosion resistance, for most devices, he does not take additional protective measures, even if the metal sheath of the cable is susceptible to chemistry Corrosive or industrially polluted areas. Because the cable is protected by a plastic outer jacket at the outermost layer, he is still safe.

8) High mechanical strength (Mineral insulation flexible isolating cable is sturdy and durable, throwing can work normally if the cable diameter is deformed by one-third of the cable, even if subjected to severe mechanical damage, it will not damage its electrical performance.)

9) Because of the advanced, the production efficiency is high. The scrap rate is low, and the delivery cycle of NGA (BTLY) mineral insulated flexible (isolated) cable can fully meet the requirements.
