Abstract

The utility model-an ultraviolet light cross-linking apparatus for manufacturing electric wire and cable is characterized in that its ultraviolet illumination box is composed of a plurality of non-polarized lamp modular units which are arranged in sequence along the direction of the central axis of the cables waiting for cross-linking and are uniformly distributed on the spacing circumference to some distance from the central axis. Each modular unit is a stand-alone illumination system equipped with a microwave excited non-polar ultraviolet strip lamp. The backside of the strip lamp is equipped with a reflector with a cooling medium entrance on top which is moveably connected with the air feeder. The power density of the non-polarized lamp modular unit adopted by the ultraviolet illumination box in the utility model adopts is 2-3 times as much as that of the traditional high-voltage mercury lamp. It greatly increases the production rate of the light cross-linking cable and the thickness of the uniform crosslink. It is not only able to produce the crosslink electric wire and cable with low-voltage, but it can also be the same with producing the crosslink electric wire and cable with middle and high voltage in the thick insulating barrier.

Description

A kind of production electric wire ultraviolet light cross-linking equipment
Technical field:
The utility model belongs to the cross-linked wire and cable production equipment, particularly relates to the ultraviolet lighting case of producing the ultraviolet light cross-linking equipment that electric wire uses.
