BTLY Flexible Aluminum Sheath Continuous Extruded Mineral Insulated Cable
This series of cables has a wide coverage, overcoming the shortcomings of rigid mineral insulated cables and leveraging the advantages of flexible mineral insulated cables. It also provides practical products for various key projects, enabling modern engineering to achieve the effect of short circuit non combustion and combustion non short circuit in electrical circuits; Not only can it be successfully applied in fire-resistant performance such as fire alarms and emergency rescue circuits, but it can also be promoted and applied in high-density current and other special performance requirements. Suitable for power supply circuits of fire protection systems, densely populated places such as large shopping malls, hospitals, subways, etc. that require high fire resistance performance.
