Introduction to Instrument Cables

Instrument cables are equipment used for signal transmission and control circuits in instruments, instruments, and other electrical equipment.

Instrument cables refer to wire products used to transmit electrical energy information and achieve electromagnetic energy conversion. It consists of basic components such as conductors (wires), insulation layer, shielding, insulation core, protective layer, etc. According to different needs, wires and cables are an integrated body composed of some or all of the above components. Used for power supply, transmission and distribution, motor, electrical appliances, and electrical instrument winding to achieve electromagnetic energy conversion; Measure electrical and physical parameters; Transmission of signals, information, and control; Used for shared antenna television or cable television systems; Used as a feed line for transmitting and receiving antennas in wireless radio stations or as a connection line for various RF communication and testing equipment.

classification

1. Signal instrument cables

High anti-interference ability, stable electrical performance, capable of transmitting digital and analog signals at AC 300V and below. The flame retardant performance of instrument cables (oxygen index ≥ 30) can refer to other performance indicators of signal cable basic models: YVV, YVVP, RVV, RVVP.

2. Control cables

Control instrument cable: Product execution standard: Q/HTTZH008 flame retardant characteristic test follows GB12666.5-90 standard instrument control cable: Product characteristics and usage are suitable for instrument control cable products with AC rated voltage of 450/750 and below. The shielding cable for patrol inspection devices adopts twisted aluminum plastic composite film shielding and copper wire weaving shielding, with superior anti-interference performance and is widely used in computer measurement and control devices. Basic models: KJVVP3R, KJVVP3, KJVVP2R, KJVVP2, KJVVPR, KJVVP, KJYVP3R, KJYVP3, KJYVP2R, KJYVP2, KJYVPR, KJYVP.

3. Computer cables

This product uses K-type B-type low-density polyethylene with antioxidant properties. Instrument cables are suitable for electronic computers and automation connection cables with a rated voltage of 500V and below, which have high anti-interference requirements.

Usage characteristics

The rated AC voltage of the cable is below 500V, and the long-term working temperature of the cable core should not exceed 70 ℃. The allowable bending radius of the cable should not be less than 6 times the outer diameter of the cable, and the laying temperature should not be lower than 0 ℃.
