Anhui Tianming Cable Co., Ltd. === Computer Cable WDZN-DJYYP23 Low-smoke Halogen-free Flame-retardant Computer Cable Sheathed Computer Cable This product boasts excellent flame-retardant properties, emitting very little smoke during combustion and no corrosive gases. It is widely used in nuclear power plants, subway stations, telephone exchanges, computer control centers, high-rise buildings, hotels, broadcasting stations, important facilities, oil platforms, and other locations with high personnel density and low air density. The computer shielded cable uses high-voltage polyethylene with a small dielectric constant as insulation. It employs structures such as twisted pairs, shielded pairs, overall shielding (or three-wire combinations, group shielding, group overall shielding), featuring low dielectric loss, strong transmission capability, and good anti-interference performance. It can reliably transmit weak analog signals and is extensively applied in computer systems or automation devices for detection and control in power generation, metallurgy, petroleum, chemical industry, light industry, and textiles, as well as general industrial computers.
