Specialized Nitrogen Generator For Cable Industry

The specific application of nitrogen in the cable production industry is to use polyethylene insulation material with added peroxide crosslinking agent. After extrusion of the conductor shielding layer, insulation layer, and insulation shielding layer through three-layer co extrusion, the cross-linking process is continuously and uniformly completed through a sealed crossover pipe filled with high temperature and high pressure nitrogen gas. The heat transfer medium is nitrogen (inert gas), and cross-linked polyethylene has excellent electrical properties and a production range of up to 500KV.

When the air in the pressurized through the purification and drying, Base on Aerodynamics, nitrogen and oxygen in the air in the zeolite molecular sieve (ZMS) on the Pressure swing adsorption  will performance of different diffusion rate through the adsorption of nitrogen. Oxygen in carbon molecular sieve on the surface of the diffusion rate is higher than nitrogen. When the adsorption was not in balance, oxygen was absorbed by carbon molecular sieve in large quantity, and nitrogen was concentrated and enriched in the gas phase to achieve separation of oxygen and nitrogen.
