Abstract
The invention belongs to the technical field of cable manufacturing and provides an environment-friendly fire-proof waterproof type variable frequency cable. Fire-proof layers wrap phase line conductors and null line conductors respectively, the fire-proof layers adopt two-side mica tapes, and therefore the electrical performance and the usage performance of the variable frequency cable on the condition of flames are ensured. Gaps inside cable cores are covered with insulation filters, a radial water-blocking packing layer is arranged outside the cable cores, and the radial water-blocking packing layer is wrapping water-blocking tapes which are overlapped, can play a role in water blocking during water intrusion, and can buffer and isolate heat energy transmitted from the outside; the radial water-blocking packing layer is wrapped with an oxygen isolating layer, a protective layer and an outer protective layer in sequence, the oxygen isolating layer and the outer protective layer are respectively made of halogen-free materials to effectively avoid secondary damage, the protective layer wraps the oxygen isolating layer in an interval and overlapping mode and can effectively prevent fire, plastic cement is fused into a whole when the flames exist, and therefore the effect of water blocking is achieved. The environment-friendly fire-proof waterproof type variable frequency cable is fire-proof, waterproof and environmentally friendly, and effectively ensures the safe reliability of circuit work.
