Coaxial cable, Shanghai manufacturers offer

Slightly coaxial high frequency digital transmission equipment, switching equipment, limited unlimited access network and the mobile communication signal suitable for transmission, can also be used for radio, broadcast radio frequency signals and other common electronic specifications of the coaxial cable models are as follows: coaxial cable divided into two basic types, baseband coaxial cable and broadband coaxial cable. Currently baseband common cable, which shield is made of copper mesh, the characteristic impedance is 50 (e.g., RG-8, RG-58, etc.); broadband coaxial cables commonly used shield is usually stamped aluminum into a characteristic impedance of 75 (such as RG-59, etc.). Which consists of coaxial cable inside out followed by copper, plastic insulation, metal mesh nets and plastic sheath and shield composed of copper and conductor of the coaxial network, named coaxial cable. Radiating metal screen center conductor of this structure can prevent the electromagnetic field, the signal can also be used to prevent external electromagnetic interference of the center conductor. 2, coaxial cable parameter index (1) characteristics of the main electrical parameters * coaxial cable impedance; · coaxial cable attenuation; propagation speed coaxial cable ·; · coaxial DC loop resistance. (2) physical parameters of the coaxial cable; open condition (3) of the main parameters of the test cable · conductor or shield. · Short circuit between the conductor and the shield. · Grounding conductor. · Between the shield connector of a short circuit. From the use of coaxial cable can be divided into baseband coaxial cable and broadband coaxial cable (ie, coaxial and video coaxial cable network). [1] and coaxial 50Ω and 75Ω baseband cable broadband cable types. Baseband coaxial cable is divided into fine and coarse coaxial cable. Baseband cable only for digital transmission, data rates up to 10Mbps. Coaxial cable (Coaxial) refers to two concentric conductors, while the conductor and the shield to share a common axis of the cable. The most common insulating material isolated coaxial copper conductors. RRT addition to product quality excellent, there is a major feature that is service. Those who have worked and RRT customers have personally feel our sincere service. Whether or not worked with clients who are active in providing relevant information and product inspection reports to facilitate customer engineering standard case, which not only reinforces the old customers, but also brings a lot of potential customers. They made a resounding "quality, price and service is our reason for your choice" slogan, this is not an empty slogan, but a reflection of our strength and value.
