I. Introduction This product is suitable for rated voltage 500V and below for the anti-interference requirements of computer and automated connection cable. Ground cable core edge computer cables used must have antioxidant properties of K-type class B low density polyethylene. Polyethylene, high insulation resistance, good resistance to voltage, dielectric constant and dielectric loss of small temperature and variable frequency effect is small, not only to meet the transmission performance requirements, but also to ensure that the cable life. In order to reduce the circuit crosstalk and external interference, shielded cable structure. Cable shielding requirements are based on different occasions were used: shielded twisted pair combination, composed of twisted pair overall shielded cable, shielded twisted pair combination after the total shielding and other methods. Shielding materials are round copper wire, copper, aluminum / plastic composite tape three. Shielded with the shield has good insulation properties of the cable in use shield, if shield against potential difference between, it will not affect the signal transmission quality. Second, the technical parameters Rated voltage (U0 / U): 300/500V long-term working temperature is 70 ℃ The ambient temperature is not lower than: Fixed laying -40 ℃, non-fixed installation -15 ℃ Minimum bending radius: unarmored should be less than six times the cable diameter, with armored cable should be not less than 12 times the cable diameter at 20 ℃ 500V dc charging voltage test stability after 1min Insulation resistance shall be not less than 2500MΩ · Km of each twisted pair shielded room and shielded twisted pair with overall shield should continue between the cable cores and the road between the core and the shield wire should be subjected to between 50HZ, 2000V AC voltage test without breakdown factory 5min solemnly declare: 1, signed product quality assurance , promise - no unqualified products factory. Within two years, product quality tracking service, and customer service records in the archives of 20 years. 3 Ensure product quality problems, I will plant the warranty, refund, replacement, to meet customer requirements. Specifications: According to customer requirements Quantity: MOQ is 100 m, 100 m -200 m prices go up Packing: a few meters short of the disc packaging, a few meters long cable shaft packing Price Description: Phone negotiated price based on decline in copper prices go up at any time Updates Contact Sales Department (General Manager) Revise office phone number 15731627778 15731627778 landline 0316-5726723
