[Shanxi Xinzhou lightning protection and grounding materials and stable performance copper clad steel wire copper clad steel wire] Identification To identify copper clad steel wire, it must first understand the internal structure of the outer cladding layer of copper, with the naked eye is difficult to Identification quality, but can be used to detect special testing equipment conductivity, and the copper layer thickness. Copper clad steel strand measures to prevent electromagnetic induction, along the poles on the camera power lines and signal lines should be worn in the metal tube in order to achieve shielding effect, the shield should be grounded at both ends of the metal tube. Along the road to prevent lightning invasive front-end equipment, the equipment should be installed in front of each line suitable arrester, such as power lines (DC24V or 220V), video cable, signal cable and PTZ control lines. signals long distance transmission lines, voltage level is low, vulnerable to lightning currents and damage to the equipment, in order to lightning current from the signal transmission lines pass import, the signal over-voltage protection device shall respond quickly, in the design of the signal transmission line protection must consider the actual situation, according to the signal transmission rate, the signal level , start voltage, and other parameters such as flux lightning select the correct lightning protection equipment. headend equipment such as cameras should be placed air terminals (lightning or other lightning conductor) within the scope of effective protection when the camera is set up independently, in principle, to prevent lightning and high voltage transients on the deflectors, lightning best 3-4 meters away from the camera and if lightning can also be difficult to set up the camera on a support bar, rod deflectors can be directly used by itself or optional Φ 8 galvanized round steel company official website: http://www.egangjiaoxian.com/ Mobile: 18713765028 18632765994 Tel 0317 -8349587 Contact: Chang Manager Address: Botou City Yuhua Road I always equal on the basis of mutual benefit with customers at home and abroad to establish long-term friendly business relationships, the company in good faith, the quality of survival, reputation and development, honesty, dedication to the community spirit of innovation and a highly efficient, high-quality lightning protection products warmly welcome Chinese and foreign customers call us to discuss!
