Abstract

The invention relates to a high-reliability environmental-friendly aluminium alloy power cable which comprises an alloy conductor, a lapped covering, an insulating layer, a shielding lapped covering, a filling layer, a lining lapped covering, an armor layer and an outer sheath, wherein the lapped covering is lapped outside the alloy conductor; the insulating layer is extruded outside the lapped covering; the shielding lapped covering is lapped outside the insulating layer; the filling layer coats the shielding lapped covering; the lining lapped covering is lapped outside the filling layer; the armor layer coats the lining lapped covering; and the outer sheath is extruded outside the armor layer. The high-reliability environmental-friendly aluminium alloy power cable provided by the invention adopts special multilayer structural design, a novel cable material and the specially-made filling layer. The high-reliability environmental-friendly aluminium alloy power cable provided by the invention has the prominent characteristics of non halogen and low smoke and low halogen and low smoke, and thus, in the case of a fire, a spreading speed is low, smoke concentration is low, visibility is high, and a release volume of harmful gas is small, so that the high-reliability environmental-friendly aluminium alloy power cable is convenient for people to evacuate. Combustion gas is low in corrosivity, and damage to instrument equipment is also avoided. Aging resistance, ultraviolet resistance and other irradiation properties of a material of the cable provided by the invention are greatly improved, so that the service life of the cable is prolonged.

Description

technical field [0001] The invention relates to a cable, in particular to a high-reliability environment-friendly aluminum alloy power cable. Background technique [0002] The materials of environmentally friendly wires include insulating materials, conductor materials, and shielding materials. Insulation such as polyvinyl chloride (PVC), radiation cross-linked polyvinyl chloride (XL-PVC), radiation cross-linked polyethylene (XL-PE), low smoke halogen-free (Halogen-free), silicone rubber, Teflon teflon and so on. The environmental protection of insulating materials is currently mainly 6P (Non-6P), that is, phthalate-free, as required by the EU's RoHS environmental protection directive and the EU's environmental protection regulations on children's toys. And now the most environmentally friendly is low-smoke and halogen-free, which does not contain halogen elements at all. [0003] Conventional cables are quite polluting, and a large amount of dioxins, lead, cadmium, halid...
