Abstract

The invention discloses an insulation oxygen-isolation high-flame-retardancy power cable which comprises a cable core, the cable core is formed by twisting four insulating wire cores; the gap of the cable core is filled with a flame-retardant glass fiber band, a metal shielding tape is extruded outside the cable core, a first high electrical calcined clay flame-retardant layer is extruded outsidethe metal shielding tape, a flame-retardant corrugated composite paperboard is arranged outside the first high electrical calcined clay flame-retardant layer, an oxygen-isolation layer is arranged outside the flame-retardant corrugated composite paperboard, and a second high electrical calcined clay flame-retardant layer is extruded outside the oxygen-isolation layer, a metal armoring layer is arranged outside the second high electrical calcined clay flame-retardant layer, and a halogen-free low-smoke flame-retardant inner sheath is extruded outside a metal armor layer. The cable has the advantages of being good in shielding performance, good in anti-interference performance, good in insulativity, good in flame retardancy and fire resistance.

Description

technical field [0001] The invention relates to the field of cables, in particular to an insulating and oxygen-insulating high flame-retardant power cable. Background technique [0002] With the development of the power industry, DC cables are more and more used in various fields, such as subways and nuclear power plants, due to their high transmission rate and small line loss; convenient adjustment of current and change of transmission direction; low installation and maintenance costs. The safety and reliability requirements of electrical equipment such as shopping malls, hospitals, and intelligent buildings are getting higher and higher, and it is urgent to develop a new generation of environmentally friendly DC cables. [0003] With the frequent occurrence of fire accidents, people's awareness of the fire hazards of wires and cables continues to deepen, and the relevant departments have higher and higher requirements for the performance of wires and cables such as fire re...
