0.6 / 1KV حريق كابل غير العضوية المعدنية معزول معدني غمد

0.6/1KV Fireproof Cable Inorganic Mineral Insulated Metallic Sheath Flexible mineral insulated cable BTLY (isolation) cable fire prevention Because fire cable are all with inorganic (copper and magnesium oxide powder), it itself does not cause fire, impossible to burn or fire, as a result of the copper melting point is 1083 ℃, magnesia melting point is 2800 ℃, so this kind of cable can be close to the melting point of copper fire cases continue to maintain the power supply,
