Abstract
The utility model discloses an aluminum conductor power cable mainly comprising a reinforcing core, aluminum conductors, inner insulation shielding layers, an outer insulation shielding layer, copper conductors, an aluminum belt armor layer, a copper belt armor layer and shielding sheath layers. The center of the aluminum conductor power cable is provided with the reinforcing core. The plurality of the aluminum conductors are twisted together and wrap the reinforcing core in an extruded manner, so that an integral body is formed and the integral body is wrapped with the inner insulation shielding layer. The inner insulation shielding layer is wrapped with the outer insulation shielding layer. The copper conductors are wrapped with the outer insulation shielding layer in an extruded manner. The outer insulation shielding layer is wrapped with the two armor layers. The aluminum conductor power cable is applied to industries such as metallurgy, electric power, chemical engineering, papermaking and the like and is especially applicable to electric lines with comparatively heavy electromagnetic interference. The aluminum conductor power cable is long in service life time and has characteristics of being high in anti-electromagnetic interference and high in tear resistance.
