Cross-Linked Linear Low Density Polyethylene Cable Material

Product Description

The LED light sources were mounted in a tunnel structure. The light radiated the center of the tunnel where the manufactured wire and cable go through. The radiation power can be set from 0 to 100% smoothly.Optical lens adopts imported ultraviolet fused quartz and vacuum coating technology, which greatly improves the utilization rate of ultraviolet energy.  The advantages of UV-LED system over traditional UV lamp system and electron beam radiation and crosslinking:
vLow energy consumption :UV-LED system is only consume 1/4 energy comparing that of traditional UV lamp system at same production,1/30 energy comparing that of electron accelerator.
vFast production:Compare to crosslinking, and consigned electron beam processing, the crosslinking processing is finished simultaneously with the extrusion.
Low production cost:No intermediate movement and storage of the product, save the human power and additional cost. Low cost of UV radiation compound.
vLong life expectancy of the system :Life expectancy of the LED device is 4000 hours,no bead loss in normal working environment, and the perfect output power stability, See the life comparison table.
Environment friendly:The wave length is only 5nm band width, no short wave length UV energy induced Oz emission, no infrared and heat radiation, no strong visible light pollution. Ozone discharge is included into Emission standards for odor pollutants,US stipulate 0.1ppm, China stipulate 0.15ppm,UVL-I equipment won't products ozone.A water cooling system and a 2kW air blower are needed for extracting small molecule emission from the material during extrusion to keep the tunnel clean.
vSmall in size, easy to installation: The system can be inserted in traditional plastic insulating extruding production line, 1.8-2.0m in length and 2.5-3.0m in width in between extruding die and water trouph, water cooling system can be arranged properly.
Easy to operation :Pneumatic turn open and close the tunnel structure, make the conveying of the wire and clean the lens easy and ordinary operator can do it.
Low cost of maintenance:No lamp should be change, and no reflector should be replaced. The daily maintenance is only the clean of the lens surface by soft paper. For electronic beam system, maintenance is a heavy task.
