No intermediate joint

Mineral insulated flexible fire-resistant cable can be produced in fixed lengths according to customer requirements, without intermediate joints, reducing the cost of joints and improving the stability of the cable.

Short delivery time

The use of advanced production technology and mature manufacturing technology, so that the cable delivery cycle is short, often specifications can be delivered within 7 working days after the contract.

Voltage Rating

Mineral insulated flexible fire-resistant cables are available in voltage classes up to 0.6/1 KV.

Flexibility

The mineral insulated flexible fire-resistant cable uses stranded conductors and a non-metallic sheath, making the cable more flexible and lighter in weight.

Rodent and ant resistant

Mineral insulated flexible refractory cable is produced continuously without joints, which effectively prevents damage to the cable by rodents and ants.

Wide coverage

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

Easy installation

Due to the combination of mineral insulated flexible fire-resistant cable and traditional cable production technology, it makes the installation and laying of the cable more convenient and avoids the wiring termination problem often encountered with mineral insulated cable (BTTZ ).

Low line loss and high load capacity

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

Energy saving and environmental protection

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

Radiation-proof' high safety

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

Explosion-proof performance

The highly compacted insulating material in the cable and the absence of intermediate joints prevent steam, gas and flame from entering the electrical equipment connected to the cable, making it suitable for use in places where there is a risk of explosion and for connection of various explosion-proof equipment and devices.

Super flame resistance

Mineral insulated flexible fire-resistant cable has super flame retardant, the biggest difference in the design of the general flame retardant cable structure is to have inorganic metal hydrate such as aluminum hydroxide magnesium hydroxide instead of the traditional polypropylene rope or glass fiber, metal hydrate in the flame into metal oxides and water, not only to reduce the temperature of the burned cable and

Its residues are densely wrapped in the insulation core outside, so that it can not participate in the thermal oxygen reaction, so even if the laying of such cable capacity of more than 28L / m will instantly self-extinguishing (its charring standard has 2.5m reduced to less than 1.0m).
