EN50264 High temperature heat resistant and fire resistant wire &cable
High temperature heat resistant and fire resistant cables can maintain safe operation for a certain duration in the event of flame combustion. They comply with the European standard EN50264. Irradiated cross-linked polyethylene offers several advantages, including high temperature resistance and stable electrical, mechanical, and chemical properties. The use of low-smoke, halogen-free, flame-retardant materials and structures significantly enhances the safety and environmental friendliness of the cables.
