Abstract

The invention discloses a production process of a high insulation halogen-free low-smoke plastic electric wire for a photovoltaic cable. The production process comprises the following technical steps: (1) parameter setting before production; (2) selection of a screw; (3) selection of a die; (4) baking; (5) setting of temperature of each section of an extruder during working; (6) selection of a die; (7) setting of extruding velocity; and (8) finished product cooling. Compared with the prior art, the production process has the following advantages of: (1) strong operability; (2) better product stability compared with the traditional extrusion production process; (3) high production efficiency and (4) great reduction of rejects.

Description

technical field [0001] The invention belongs to the technical field of plastics, and more specifically relates to a production process of a high-insulation, halogen-free and low-smoke plastic wire for photovoltaic cables that meets the US UL5703.
