Rated 0.6/1kV and below, these metal-sheathed non-organic mineral insulated cables are used in both industrial and civil construction, boasting excellent fire-resistant properties. Their耐火等级 not only meets the requirements of the GB/T 19216.21 standard's 950℃~1000℃/90min circuit integrity test, but also complies with the British BS 6387 standard for simple fire resistance, fireproof waterproofing, and impact resistance. They are flexible, allowing the cable to be coiled on a drum, with a bending radius of 6-10D. They produce no smoke or toxic fumes during combustion, making them an environmentally friendly green product.
