1. The advantages of flexible fire protection cable > > >

1. The fireproof performance, fire resistance rating not only meet the national standard GB12666.6 class A 950 ℃, 90 min, also can meet the UK BS6387-1994 specified in A level 650 ℃ 3 h; B 750 ℃ for 3 h; C level 950 ℃ 3 h requirements; At the same time, also tolerated in the combustion of water jet and mechanical impact;

2. Continuous long length, whether single core, or a multi-core cable, its length can meet the requirements of power supply length, the length of each row of up to 1000 m;

3. The big cross section, 2 single core cable up to 1000 mm, multicore cable up to 240 mm 2

With flexible cable can be set on the cable, the bending radius of 20 D, or less for the cable diameter (D);

4. Has a flexible cable can be set on the cable, the bending radius of 20 D, or less for the cable diameter (D)

5. When burning smoke-free non-toxic, insulation with inorganic materials (not burning body), does not produce any harmful gases during burning, more is not going to happen, the second pollution is a green environmental protection products.

6. Large overload capacity, the cable is not only carrying capacity is big, and has large overload capacity. Can according to the wiring, cable surface temperature of 70 ℃ or less normally, if the wiring shall touch, also not contact with combustible construction materials, cable sheath temperature to 105 ℃ can be improved. When overload fire cable long-term working temperature can reach 250 ℃;

Corrosion resistance, organic insulating refractory cables sometimes need to wear plastic or iron pipe, plastic pipe aging become fragile, iron pipe is easy to rust, fire retardant cable with copper sheath need not to wear tube, copper sheathed good corrosion resistance

8. No electromagnetic interference, fire prevention, information and control cable laying in the same shaft, under the shield of the copper sheath, not on the signal, control of wire and cable transmission information interference;

2. Refractory characteristics of flexible fire protection cable > >

1. According to the GB12666.6

A. class combustion in the flame temperature 950 ℃, and white and 750 v voltage applied between the outer sheath, with over 90 min insulation is not damaged.

B. classes and combustion in the flame temperature 750-800 ℃ and 750 v voltage applied between sheath, with over 90 min insulation is not damaged.

2. According to the British BS6378 standard, flexible fire cable can meet the following requirements:

A. level 650 ℃ for 3 h

B. level 750 ℃ for 3 h

C. 950 ℃ for 3 h

S. level 950 ℃ for 20 min

Insulation is not damaged.

3. Good safety, fire prevention can the flame to the normal power supply cable, starting the fire fighting equipment, reduce fire loss, also special for the personal safety and reliable, its copper sheath is a good conductor, grounding is the best PE line, and continuously to the cable length, greatly improving the earthing protection sensitivity and reliability.

4. Long service life, high temperature resistant inorganic insulation material, and not easy to aging, his life many times higher than the organic insulated cable, under normal working state, can its life with the building;

5. The flexible fire cable transportation and installation, including installation accessories similar to ordinary cable, is relatively simple;

6. Economical, flexible fire cable due to advanced production technology, simple installation, under the same conditions the comprehensive cost significantly lower than the cost of mineral insulated cable.

Electrical characteristics of flexible fire protection cable > >

1. The rated voltage: 0.6/1 kv;

2. The rated operating voltage: light load 500 v, overloading 750 v; Breakdown should not occur.

3. The current rating: single core 25-1800 - a, a multicore 16 a - 500 - a;

4. The insulation resistance: insulation resistance 1000 m or more Ω · km. Cable length is less than 100 m, 10000 m or higher insulation resistance Ω;

Level 5. Power frequency withstand voltage: 500 v and 750 v cable respectively 2000 v and 2500 v voltage in phase, phase between copper sheath, 15 min, breakdown should not occur.
