Abstract
The utility model discloses a composite tape wrapped fireproof power cable. Each conductor is made by twisting a plurality of soft copper wires. A ceramic fireproof composite tape is wrapped with overlap on each conductor to form a fireproof layer. A polyolefin insulating layer is extruded on each fireproof layer to form a wire core. The plurality of insulating wire cores are twisted to from a cable core. Two layers of the ceramic fireproof composite tape are wrapped outside the cable core to form a wrapping layer. An outer sheath layer is extruded on the wrapping layer. The composite tape wrapped fireproof power cable has excellent heat-resistant and temperature-resistant properties, and is characterized by being flame-retardant, halogen-free, nontoxic, and low-smoke.
Description
Technical field
The utility model relates to a kind of power cable, relates in particular to the wrapped fireproof power cable of a kind of composite band, belongs to technical field of electric wires and cables.
