What are the advantages of BTLY cables?
1. BTLY series mineral insulated cables are available in sizes from 1.5 to 6 mm², with 3 to 61 cores; sizes from 95 to 240 mm², with 1 to 5 cores; and sizes from 240 to 630 mm², with single cores. Lengths can be customized to meet customer needs, and they can be delivered as whole cables without joints.
2. BTLY series mineral insulated cables do not require separate conduit for installation and offer the same waterproof and impact resistance as BTT cables. They are also resistant to termites, rodents, and radiation, ensuring greater stability, longevity, and durability. With low operating temperatures, low line loss, and strong overload resistance, they offer a long service life and high safety, making them particularly suitable for projects with environmentally friendly requirements.
3. The metal sheath of the BTLY series mineral insulated cables is highly corrosion-resistant, eliminating the need for additional protective measures in most installations. Even in locations where the cable's metal sheath is susceptible to chemical corrosion or industrial pollution, the cable remains safe thanks to the plastic outer sheath. BTLY series mineral insulated cables are mechanically strong and durable, capable of functioning even when deformed by one-third of their diameter. Even severe mechanical damage does not compromise their electrical performance.
4. Using aluminum as the primary metal tube extrusion material instead of copper drawing not only simplifies the process and improves efficiency, but also significantly reduces product costs (aluminum costs only 1/10 of copper). The ability to replace copper tubes with aluminum tubes, which remain resistant to high-temperature flames, is due to the intumescent fire-resistant layer extruded over the aluminum tubes. This layer foams and solidifies under flame attack, forming a thick barrier that blocks direct flames from the aluminum tubes. Not only is the integrity of the aluminum tube preserved, but the heating temperature of the mica tape is also reduced to below 600°C, and the insulation stability of the mica tape is undoubtedly improved (the insulation resistance of the mica tape increases as the temperature decreases).
