Precautions for the use of coaxial RF cables

Coaxial RF cable is a common RF cable, its good or bad directly affects the transmission of signals, coaxial RF cable precautions for use. RF coaxial cable good or bad directly affects the signal transmission and unnecessary losses, a standard RF coaxial cable cross-section is very rounded, the cable outer shield, aluminum foil affixed to the outer surface of the insulating medium, the more rounded the outer surface of the medium, indicating that its performance is better. 1. first observe the roundness of the insulating medium: a standard RF coaxial cable cross-section is very rounded, the cable outer shield, aluminum foil affixed to the outer surface of the insulating medium, the more rounded the outer surface of the medium, the aluminum foil and its exterior. The outer surface of the medium, the more rounded the outer surface, aluminum foil and its appearance of the gap is smaller, the more not rounded the gap is larger. 2. test the consistency of the coaxial cable insulation medium: coaxial cable insulation medium diameter fluctuations mainly affects the cable return coefficient, this check can be dissected out of a section of the cable insulation medium, with a micrometer to double-check the outside diameter of each point, to see if it is the same. 3. check the quality of the aluminum foil: coaxial cable plays an important shielding role is the aluminum foil, the aluminum foil, the aluminum foil, the aluminum foil, the aluminum foil and its outer surface, to see if it is good. Important shielding role is the aluminum foil, which has an important role in avoiding foreign open-circuit signal interference and preventing leakage of cable TV signals 4. check the coaxial cable braided network: coaxial cable braided mesh coaxial cable shielding plays an important role, and no matter whether it is in the centralized power supply cable TV lines or power supply circuit line, the coaxial cable quality inspection should be on the textile network whether the tight and flat carefully observed 5. detect the outer sheath of the cable, the outer sheath is the same. Observe the tightness of the extrusion of the outer sheath: high-quality coaxial cable outer sheath are wrapped very tightly, which can narrow the gap in the shielding layer to avoid air entry caused by oxidation, to prevent the relative sliding of the shielding layer caused by the electrical properties of the drift, but the extrusion of the packet is too tight, if it will result in the stripping of the head of the inconvenience and increase the difficulty of the construction. 6. Observe the cable into the shape of the circle: cable into the circle not only in the appearance of the appearance of the beautiful, but also the quality of the cable is more important. The quality of the cable is still a problem. Cable into a flat circle, each cable to maintain in the same concentric plane, cable and cable between the arc parallel to the overall contact, can reduce the cable mutual force, stacking is not easy to deformation damage.-7, on Evergrande Electronic Products Network platform related to the introduction and sales of products briefly: Evergrande Electronic Products Network - a professional agent / production / sales of a variety of {connectors | wiring harness | wire and cable products }; if you have a related [connectors | wiring harness | wire and cable products] purchasing / sourcing needs or would like to buy / to understand which connectors | wiring harness | wire and cable products we can provide solutions, please contact the following Division I business personnel; If you have related [connector | wire harness | wire and cable production] sales / resources and promotion needs, please click on the ¡¡ Business Cooperation ← ¡" to discuss with a person!
