The UV-light irradiation cross-linking process uses UV-light as the irradiation source, extrudes and coats the mixed photo-crosslinking polyolefin compound on the conductor wire core, and then immediately enters the special irradiation equipment for fused photo-crosslinking. The insulated wire core after light irradiation cross-linking can be produced into photo-crosslinking polyolefin insulated wire and cable products through cooling treatment at different temperatures and other subsequent processing. UV-light irradiation cross-linking method needs to be slightly modified only on the original normal extrusion production line. The upper traction, irradiation box and electric control cabinet with a small floor area can meet the operating requirements and produce UV-light irradiation cross-linked polyethylene wire and cable products. The addition of upper traction enables the conductor wire core to maintain a certain tension. In the running process, it shall be always in the center of irradiation box to ensure the best irradiation effect. The irradiation box uses a reflective focused UV light source that is uniformly configured and specially designed, and the electrical control system will ensure that the UV-light intensity and the irradiation temperature in the center of the irradiation box are in the optimum operating conditions. In addition, the efficient photo-initiation system rapidly induces cross-linking reaction of polyolefin under the UV-light irradiation, so that the irradiation equipment can reach a continuous production speed of dozens of meters per minute, and gradually cools at hot, warm and cold temperatures to ensure the stability of three-dimensional cross-linked netlike structure.

LED light.
For the Mosquito killer Led Bulb Light, is a 900 lumen bulb that doubles as an insect killer. The light features a blue UV LED which attracts insects into a Mosquito Killer grid.And the Mosquito Killer grid uses only 1W of electricity, while the light itself uses a meager 9W – and both can be used independently.They are used at home and outdoor. A brush is provided to clean off insects once the bulb switched-off.Compare to other traditional mosquito killer, this bulb has no chemicals, no sprays and hence no fumes to our life. 2nd generation 2-in-1 LED LIGHT Bulb Plus LED Mosquito Killer Bulb Wattage: 10W Blue UV light Lumen: 900-1000lm Color Temperature (CCT): 6500K Input Voltage: AC 90-130V & 220v-240V With CE and ROHS Operation: Step1: Switch it on,both lighting +killing are on. Step2: Switch on again,light off,only killing on. Step3: Switch on again,killing off,only light on. Step4: Switch off, both off.
