How to ground the network cable shielded cable

　　The grounding of the network cable shielded wire is an important link, which is related to the stability and anti-interference ability of the network signal. The following are the detailed steps and precautions for grounding the network cable shielded wire:

　　First, the grounding step

　　Prepare tools and materials:

　　Ground wire: Usually copper or tinned copper wires are used to ensure good electrical conductivity.

　　Grounding clamp or ground screw: used to fix the ground wire to the ground terminal.

　　Wire stripping pliers: used to remove the outer skin of the shielding layer of the network cable.

　　Crimping pliers (optional): Use if the ground wire needs to press the crystal head or other connectors.

　　Connect the shielding layer:

　　Use wire stripping pliers to peel off the outer skin of the wire shielding layer to expose the inner metal woven mesh or aluminum foil layer.

　　Peel the shielding layer a certain length to connect with the ground wire. Be careful not to peel it too long to avoid exposing too many signal wires.

　　Use a ground wire to securely connect the shield to the ground terminal of the network device. It can be secured using a ground clip or a ground screw.

　　Check the grounding effect:

　　After grounding, professional equipment should be used to detect the grounding resistance to ensure good grounding effect. The grounding resistance value should meet relevant standards, usually less than 4 ohms.

　　Make sure the grounding wire is firmly connected to avoid loosening or falling off.

　　Grounding method

　　Single point grounding:

　　Suitable for low-frequency signal environments.

　　Connect all shielding layers to the same ground point of network equipment to avoid the formation of loop currents and reduce interference.

　　Multi-point grounding:

　　It is more common in high-frequency signals or long-distance tranSMissions.

　　Grounding in multiple locations of network equipment allows for more efficient dispersion and elimination of interference.

　　It is necessary to take care to avoid forming a potential difference between different ground points, otherwise a circulation may occur, affecting the signal quality.

　　III. Precautions

　　Avoid direct contact between the shielding layer and the power cord.

　　Prevent short circuits or the introduction of new sources of interference.

　　To maintain the integrity of the shielding layer:

　　When removing the shielding layer, be sure not to damage the internal signal lines.

　　After the shielding layer is peeled off, it should be connected to the ground wire as soon as possible to avoid prolonged exposure to air.

　　Select the appropriate ground path.

　　Make sure the grounding path is as short and direct as possible to reduce grounding resistance and interference.

　　Adhere to safety regulations:

　　When conducting grounding operations, relevant safety regulations and operating procedures should be followed to ensure personal and equipment safety.

　　Detect the grounding effect:

　　After grounding, professional equipment should be used to detect the grounding resistance and shielding effect to ensure compliance with relevant standards and requirements.

　　Through the above steps and precautions, the correct grounding of the network cable shielded cable can be ensured, thus improving the stability and anti-interference ability of the network signal.
