The BTLY cable is an advanced fire-resistant mineral insulated cable with an aluminum sheath designed to overcome the limitations of cable length and intermediate joint issues in installations. This cable is highly regarded for its fire resistance, mechanical strength, high temperature tolerance, and waterproof capabilities. The BTLY cable offers superior protection against fire, electric shock, and mechanical damage, ensuring safety in high-risk environments.
It is commonly referred to as a mineral insulated cable with aluminum sheath insulation, which ensures higher safety and functionality in demanding environments. BTLY cables adhere to the BS6387 standard in the UK, which guarantees that the cable will continue to function for at least 3 hours during a fire, providing critical time for personnel and property rescue.
Key Features of BTLY Mineral Insulated Cable
Fire Resistance:
The BTLY cable is made of inorganic materials, including a magnesium oxide insulation layer and aluminum sheath that make it fire-resistant. It adheres to the BS6387 standard, allowing it to survive in fire conditions and continue operating, providing essential time for rescue operations.High Overload Protection:
BTLY cables have high overload tolerance, making them resilient to large currents and short-circuit faults. Unlike standard cables, they do not catch fire when subjected to load changes or short circuits.Flame Retardant:
With its inorganic or inorganic compound materials, the BTLY cable prevents the spread of fire and does not propagate flames to surrounding areas.High Current Carrying Capacity:
Compared to other cables with the same cross-sectional area, the BTLY cable can carry higher currents, making it an ideal choice for heavy-duty and power transmission applications.High Voltage Resistance:
This heavy-duty cable boasts a high voltage tolerance of up to 1000V, which is higher than traditional rigid mineral insulated cables.Explosion-Proof:
The BTLY cable can be produced in fixed lengths without intermediate joints, providing an effective barrier against the transmission of flammable oil vapors, combustible gases, and flames.Superior Insulation:
The cable offers excellent insulation performance even above short-circuit temperatures, ensuring high fire resistance and continuous operation for up to three hours in fire conditions.High-Temperature Tolerance:
Unlike standard cables with a typical working temperature range of 70-90°C, BTLY cables can operate in temperatures up to 250°C, making them ideal for environments with extreme temperature conditions.Waterproof:
The BTLY cable features a seamless metal sheath that provides waterproofing, enabling continued operation even in water-saturated conditions during a fire.
