Mineral flexible insulated fire resistant cable

1. NGA(BTLY) new aluminum alloy sheath mineral insulated cable structure:

(1) Copper conductor:The conductor is round copper strand

(2) Gold mica with insulation:the insulation layer is pure gold mica belt (no longer composed of extruded insulating material, so as to eliminate the generation of carbon particles and improve the electrical stability)

Mineral insulated flexible (isolated) cable performance description:

Product structure:

1. NGA(BTLY) new aluminum alloy sheath mineral insulated cable structure:

(1) Copper conductor:The conductor is round copper strand

(2) Gold mica with insulation:the insulation layer is pure gold mica belt (no longer composed of extruded insulating material, so as to eliminate the generation of carbon particles and improve the electrical stability)

(3) Aluminum alloy metal sheath:metal sleeve aluminum alloy isolation layer (can be used for grounding)

(4) Cross-linked isolation:isolation sleeve (cross-linked insulation)

(5) Mg(OH) or AI(OH) refractory layer (6) Halogen-free low smoke polyolefin outer sheath: Refractory layer (inorganic material -Mg(OH) or AL

(6) Outer sheathing plastics (polyolefin or polyvinyl chloride)

Products Features

1. The fire resistance standard can pass the British BS6387 three tests: namely, no breakdown under 3h flame at 950℃, 15min water spray after 30min at 650℃(direct immersion can also be accepted), and 15min percussion vibration without damage under flame at 950℃, so as to completely meet the test standard of BTT in terms of fire resistance.

2. The product can produce 1-37 cores with 1.5~6 square specifications, 1-5 cores with 10~240 square specifications, and single cores with 300~630 square meters.NGA(BTLY) mineral insulation flexible (isolated) cable production process used in the metal sleeve continuous molding process, so that the length of the cable can meet customer requirements, so as to achieve the whole piece without the joint of the whole plate delivery.

3. In the installation process, it can be laid in the whole section without the need of pipe piercing. It has the same waterproof and anti-impact function as BTTZ.

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

5. NGA(BTLY) mineral insulated flexible (isolated) cable core operating temperature is lower than other types of cable, so in normal operation of mineral insulated cable loss is low, saving energy consumption, especially suitable for the application of environmental requirements in the project.A large number of inorganic materials used in cables, radiation resistant.It can guarantee the stability, long life and durability of the cable, and can be used in nuclear power and other fields.

6. Explosion-proof (the highly compacting insulating material in the cable and the cable terminal installed with a special sealing sleeve can prevent steam, gas and flame from entering the electrical equipment connected with the cable, thus being used for connecting various explosion-proof equipment and equipment in the place with explosion risk.)

7. The metal sheath of NGA (BTLY) mineral insulated cable is highly resistant to corrosion and does not require additional protection for most installations.Even in places where the metal sheath of the cable is vulnerable to chemical corrosion or heavy industrial pollution, it is safe because the cable is protected by a plastic outer sheath.

8. High mechanical strength (mineral insulation flexible isolation cable durable, in the cable diameter deformation one-third of the case can still work normally, even through severe mechanical damage, will not damage its electrical performance.)
