UV LED devices are the most advanced UV radiation sources in the world, characterized by extremely high energy efficiency (about 30%), extremely high selectivity of effective wavelength (half-power wavelength broadband: 5nm), extremely long service life (40,000 hours), low infrared heat and no ozone, making them more suitable for the cross-linking and solidity of cross-linked polyolefin and other materials.
LED-UV type UV LED irradiation polyolefin cross-linked equipment adopts a circular cavity tunnel structure, installs a self-developed UV LED light source and forms a tunnel to the central area, whose radiant power can be infinitely set within the scope of 0~100%.
Compared with traditional mercury lamp type irradiation cross-linked equipment (traditional transformer-drive UV-LJ and electronic power supply-drive LSUV-LJ), electronic accelerating cross-linker and silane cross-linking, it has the following advantages:
Low cost
Low energy consumption
Short period of time
Small volume and easy installation
Easy operation
Long service life and low maintenance cost
No ozone
Green and environmental protection
