( Industry news] Cable companies attention! Copper cable with existing national standards must see! The cable line P cable is an important raw material in telecoms equipment, composed of inner conductor and an insulator, conductor and an outer sheath. Copper or oxygen-free copper strip has good conductive, thermal conductivity and stability of the welding, copper is generally selected outer conductor or oxygen-free copper production, with the development of communication technology for cable greater demands of the copper strip, copper strip thickness thinning, increase in length, precision, and at the same time to have a stable welding. For copper belt has the characteristics of high conductivity, high precision and good welding performance and on the length of the pipe production has more advantages, has been widely used in the production of the cable. In the present standard of GB/T, compared with GB/T: 1) increasing the TU, TUP. Grades and corresponding code C, and C; The upper limit (2) the thickness of the strip by '. Adjusting to the 'mm'. 毫米”; (3) to the strip width range lower limit changed from 'mm' to 'mm'; (4) to allow the strip thickness deviation modified; (5) with the allowable deviation of strip width amendment, increase the high precision level; Everyone here to clean the detailed standard of current cable with copper strip, convenient you see in the work.
