Embodiment Construction

[0016] The present invention will be described in detail below in combination with specific embodiments.

[0017] A method for producing a high-voltage electric cable, implemented according to the following steps:

[0018] Step 1, wind the cable core wire on the active pay-off frame,

[0019] Step 2, start the pay-off rack, transport the core wire to the preheater for preheating,

[0020] The preheating temperature is 100-140°C for preheating;

[0021] Step 3, the preheated cable core wires are sent to three extruders in sequence,

[0022] Specifically, first pass through the first extruder, then pass through the second extruder and the third extruder host, and sequentially coat the first insulating layer, the second insulating layer and the third insulating layer from the inside to the outside;

[0023] Step 4, transport the cables coated with the third insulation layer to the active warm water tank and the fixed water tank for cooling and shaping;

[0024] Step 5, transp...

Abstract

The invention discloses a high-voltage cable production method. The high-voltage cable production method specifically comprises the following steps of 1, winding a pay-off rack with a cable core wire;2, starting the pay-off rack and conveying the core wire to a preheater to be preheated; 3, conveying the preheated cable core wire to three extruders in sequence; 4, conveying a cable plated with athird insulating layer to a movable warm water tank and a fixed water tank to be cooled and shaped; 5, enabling the shaped cable to pass through a ranging appliance, a dual-wheel traction machine anda metering apparatus to be conveyed to a wire storage frame; and 6, conveying the cable on the wire storage frame to a dual-shaft take-up machine to be wound into a coil. By virtue of the high-voltagecable production method, the problems of low cable quantity and easy damage caused in the existing method can be solved.

Description

technical field [0001] The invention belongs to the technical field of power transmission equipment processing, and relates to a high-voltage cable production method. Background technique [0002] During the production and use of urban high-voltage cables, high requirements are placed on the quality and thickness of the insulating layer. Usually, during production, there will be uneven extrusion, resulting in weak points in the insulating layer, which will lead to the danger of leakage. Contents of the invention [0003] The purpose of the present invention is to provide a high-voltage cable production method, which solves the problems of poor cable quality and easy damage caused by existing processing methods. [0004] The technical scheme adopted in the present invention is a method for producing high-voltage cables, which is specifically implemented according to the following steps: [0005] Step 1, wind the cable core wire on the pay-off frame, [0006] Step 2, start...
