Products Description

The wires and cables used in electronic computers and electrical instrument equipment are key components used in electronic computers and electrical instrument equipment. They are responsible for transmitting electrical energy and signals to ensure the normal operation of the equipment.
The composition materials of computer cables and instrument equipment wires and cables may vary due to special requirements such as usage temperature and working environment, but usually include conductors, insulation layers, shielding layers, sheath layers, etc.
Computer cable: suitable for electronic computers and automation instruments with high anti-interference requirements for rated voltage of 500V and below. This type of cable can use insulation materials such as polyethylene, polyvinyl chloride, cross-linked polyethylene, fluoroplastics, silicone rubber, etc. according to different environments and equipment usage requirements. Instrument equipment wires and cables: used in electrical instrument equipment installations, there are multiple models and specifications to choose from according to the specific needs of the equipment.
In order to reduce mutual crosstalk and external interference between circuits, cables need to adopt shielding structures. Shielding materials include tinned or non tinned copper wire, copper tape, copper-plastic composite tape, aluminum-plastic composite tape, etc. The shielding requirements are adopted according to different occasions: partial shielding (only for twisted pairs, each twisted pair has shielding), total shielding (the cable only has one layer of total shielding after the cable core is assembled), partial shielding+total shielding (including the above two structures).

FAQ

Q1: What is the rated voltage of computer cables?
A1: The rated voltage of computer cables is 300/500V.

Q2: What are the models of computer cables?
A2: The models of computer cables mainly include DJVPVRP DJYVP, DJYPV, DJYPVP, etc.

Q3: What is the difference between computer cables and control cables?
A3: The main difference between computer cables and control cables lies in their purpose, structure, and performance. Computer cables are mainly used for connecting electronic computers and automation instruments, with good shielding performance; And control cables are mainly used for controlling and protecting circuits in industrial and mining enterprises, energy and transportation departments, and other occasions. Structurally, computer cables have slightly weaker mechanical strength and are suitable for use in indoor environments; And the control cable has high mechanical strength, making it more suitable for laying in outdoor or even underground environments.

Q4: What are the requirements for the usage environment of computer cables?
A4: When using computer cables, the ambient temperature should not be lower than -40 ℃ for fixed laying and -15 ℃ for non fixed laying. In addition, the insulation resistance of the cable should not be less than 2500M Ω· Km after stable charging with a DC 500V voltage test at 20 ℃ for 1 minute.
