3, feature description

BS6387 fire resistance

①Continuously energized for 180min under the flame of 9S0 degrees Celsius without breakdown (C)

②Under 650 degrees Celsius flame for 15 minutes, it will not break down after 15 minutes of water spray (W)

③Under 950 degrees Celsius flame, withstand 15min knock vibration without breakdown (Z)

No intermediate joint

Mineral insulated flexible fire-resistant cables can be produced according to the user's requirements, without intermediate joints, reducing the cost of joints and improving the stability of the cable.

Short lead time

Adopt advanced production technology and mature manufacturing technology, so that the supply cycle of cables is short, and the regular type can be delivered within 7 working days after the contract takes effect.

Voltage level

The voltage class of mineral insulated flexible fire-resistant cables reaches 0.6\/1 KV.

flexibility

Mineral insulated flexible fire-resistant cable adopts stranded conductor, and the sheath adopts non-metallic material, which makes the cable more flexible and light in weight.

Anti-mouse ants

Mineral insulated flexible fire-resistant cable can effectively prevent rodent ants from damaging and damaging the cable because of continuous production without joints.

Wide coverage

The length of the mineral insulated flexible fire-resistant cable can be delivered as a whole without joints according to the user's needs, which can cover almost all types of cables such as power cables and control cables.

Easy to install

Due to the combination of mineral insulated flexible refractory cable and traditional cable production technology, the installation and laying of the cable is more convenient, avoiding the wiring terminal problem often encountered by mineral insulated cables (BTTZ).

Small line loss, high current carrying capacity

Compared with cables of the same cross section, mineral insulated flexible fire-resistant cables transmit higher current than other types of cables and can withstand considerable overload. If the rated current is the same, the line loss is smaller than other cables.

Energy saving and environmental protection

The working temperature of the mineral insulated flexible fire-resistant cable is lower than that of other types of cables, so the line loss is low during work, reducing energy waste, and the cable material is inorganic, which can meet the requirements of environmental protection.

Radiation protection 39; high safety

Inorganic materials used in mineral insulated flexible fire-resistant cables, radiation-resistant. It can ensure long-term stability, long life, durability and other characteristics of the cable.

Explosion-proof performance

The highly compacted insulating material and no intermediate joints in the cable can prevent steam, gas and flame from entering the electrical equipment connected to the cable, so it is suitable for the connection of explosion-hazardous places and various explosion-proof equipment and equipment.

Super flame retardant

Mineral insulated flexible fire-resistant cables are super flame-retardant. The biggest difference in the structural design of general flame-retardant cables is that they have inorganic metal hydrates such as aluminum hydroxide and magnesium hydroxide instead of traditional polypropylene ropes or glass fibers. The metal hydrate is in flames. It is converted into metal oxides and water, which not only reduces the temperature of the burned cable, but also the residues are densely wrapped around the insulating core, making it unable to participate in the thermal oxygen reaction, so even if the capacity of such cables exceeds 28L\/m in laying Instantaneous self-extinguishing (its carbonization standard is reduced from 2.5m to less than 1.0m).
