Coaxial Cable Installation Guide Updated by Our Factory
With the continuous advancement of communication technology, the application scenarios of coaxial cables are becoming more and more extensive, and higher requirements are put forward for their installation quality. In response to the new demands of the market and users, our factory has specially updated the coaxial cable installation guide. This updated guide is based on years of production and installation experience, incorporating the latest industry standards and technical requirements, aiming to provide users with more practical and reliable installation guidance.
Installation Preparation
Tool Preparation
In addition to the traditional tools such as wire strippers, wrenches, and screwdrivers, the updated guide recommends the use of high-precision signal detectors. This detector can accurately measure the signal strength during and after installation, ensuring the quality of signal transmission. It is calibrated to adapt to the frequency range of our latest coaxial cable products, providing more accurate test results.
Environment Requirements
The updated guide specifies more precise environmental parameters. The installation environment should have a humidity of 30%-60%. If the humidity is too high, it may cause corrosion of the cable connectors; if it is too low, static electricity may easily occur, affecting the signal. The temperature should be kept between -5°C and 40°C. For high-frequency communication systems and harsh industrial environments, the installation location must be at least 3 meters away from strong electromagnetic interference sources such as transformers and motors. This is because strong electromagnetic interference will seriously affect the signal transmission of coaxial cables, leading to signal attenuation and distortion.
In terms of the installation bracket, the updated guide increases the requirement for its load-bearing capacity. The bracket must be able to bear at least 1.5 times the weight of the coaxial cable to be installed. This is to prevent the bracket from being deformed or even broken due to the weight of the cable over time, ensuring the stability of the installation.
Installation Steps
Cable Routing
When routing the cable, avoid sharp bends and excessive tension. The updated guide clearly stipulates that for our newly launched series of coaxial cables, the minimum bending radius should not be less than 10 times the outer diameter of the cable. To measure it accurately, you can use a special radius gauge. Excessive bending will damage the inner conductor and shielding layer, thereby affecting the signal transmission effect. At the same time, when laying the cable, ensure that there is no tension that exceeds the cable’s tolerance. Excessive tension will stretch the cable, resulting in changes in its electrical performance.
Connector Installation
First, use a wire stripper to strip the outer sheath of the cable according to the specified length. Be careful not to damage the inner conductor and shielding layer during the stripping process. Then, connect the connector to the cable. The updated guide provides a new type of connector installation method, which uses a crimping tool specially designed for our connectors. This tool can ensure a firm connection between the connector and the cable, reducing the risk of signal leakage. After installation, check whether the connector is installed correctly, ensuring that there is no looseness or poor contact.
Grounding Treatment
Grounding is an important part of ensuring the safety and signal stability of coaxial cables. The updated guide details the grounding operation steps and detection methods. First, connect the grounding wire of the cable to the grounding electrode. The cross-sectional area of the grounding wire should not be less than 4mm². Then, use a grounding resistance tester to test the grounding resistance, which should be less than 4Ω. If the grounding resistance exceeds the standard, check the connection of the grounding wire and the quality of the grounding electrode, and take corresponding measures to reduce the grounding resistance.
Testing and Acceptance
After the installation is completed, perform a comprehensive test on the coaxial cable system. Use the high-precision signal detector mentioned earlier to measure the signal strength and signal-to-noise ratio at different points of the cable. The signal strength should be within the specified range, and the signal-to-noise ratio should be greater than 40dB. At the same time, check whether there is signal leakage. You can use a signal leakage detector to detect around the connectors and cable bends. If signal leakage is found, recheck the installation of the connectors and the cable routing, and make corrections in time.
Maintenance and Troubleshooting
Common Faults and Troubleshooting
If the cable is short-circuited, first check the connectors. Loose or damaged connectors are the main cause of short circuits. Disconnect the connectors and check for damage or foreign objects. If the connector is damaged, replace it with a new one. If there is a foreign object, clean it up and reconnect.
If the signal is weak or intermittent, check the cable for excessive bending or damage. Use the signal detector to locate the faulty point. If it is due to excessive bending, adjust the cable routing to meet the bending radius requirement. If the cable is damaged, cut off the damaged part and reconnect it.
Maintenance Suggestions
Regularly clean the connectors. Use a dry, lint-free cloth to wipe the connectors to remove dust and dirt. Avoid using chemical cleaners, as they may corrode the connectors. Check the cable routing and brackets regularly to ensure that there is no looseness or deformation. For cables used in harsh environments, perform maintenance once a month; for cables in general environments, maintenance can be performed once a quarter.
By following this updated installation guide, you can ensure the quality and performance of the coaxial cable installation, prolong the service life of the cable, and ensure stable signal transmission.
