Abstract

The invention discloses production equipment and a production method for a composite smooth aluminum sheath cable sheath. The production equipment comprises a cable pay-off rack, an aluminum strip pay-off rack, an aluminum strip coating device, an aluminum sleeve welding device, an aluminum sleeve drawing device, a multi-layer co-extrusion device, a cooling water tank and a cable take-up device. Adouble-gun welding device comprises two welding gun modules. Each welding gun module comprises a die frame and a welding gun arranged corresponding to the die frame; the second welding gun module conducts secondary welding on a weld joint formed after welding of the first welding gun module; and the aluminum sleeve drawing device is used for reducing the diameter of an aluminum sleeve. The double-gun welding device is adopted for welding the flat aluminum sleeve, so that the weld joint is straight, and the quality of the weld joint is more reliable; and after the welded aluminum sleeve passesthrough a drawing die, the surface of the weld joint of the reduced smooth aluminum sleeve is smooth and round.

Description

technical field [0001] The invention relates to high-voltage cable production technology. Background technique [0002] In the existing corrugated aluminum-sheathed high-voltage cables, during the rolling process of the corrugated aluminum sheath, there is a certain gap between the aluminum sheath and the buffer layer, and the size of the gap is controlled according to the process. [0003] According to the existing corrugated aluminum sheath high-voltage cable process control regulations, the gap between the aluminum sheath and the buffer zone is 0.5-1.0mm. In the production process, the buffer layer is in indirect contact with the cable outer shield and the corrugated aluminum sleeve, which belongs to point contact. The shallower the corrugation of the aluminum sleeve, the poorer the contact. The structure of the semi-conductive buffer layer is composed of a layer of semi-conductive non-woven fabric and a layer of semi-conductive fluffy cotton with a thickness of about 1...
