DJYVP computer shielded cable 2 * 1.5mm voltage 300/500V

DJYVP computer shielded cable 2 * 1.5mm voltage 300/500V

Rated AC voltage U0/U: 300/500V;

Cable conductors are allowed to operate at high temperatures: PVC insulation is available in two types: 70 ℃ and 105 ℃; Polyethylene insulation at 70 ℃; Cross linked polyethylene insulation is 90 ℃ (insulation cross-linking types can be divided into silane cross-linking and irradiation cross-linking).

Flame retardant computer cables are suitable for connecting multiple pairs of shielded cables for signal transmission and detection instruments and meters in distributed systems, electronic computer systems, automation systems, and other industrial and mining enterprises such as power generation, metallurgy, and petrochemicals.

Usage characteristics: Operating temperature: generally not exceeding 70 ℃. Zui LowEnvironmental temperature: Fixed installation -40 ℃. Non fixed installation -15 ℃. The general flame retardant performance meets the requirements of GB12666.2-90; The bundled flame retardant performance meets the requirements of GB-12666.5-90; Rated voltage: U0/U: 300/500V; Small bending radius: For unarmored cables, the bending radius should not be less than 10 times the outer diameter of the cable; Armored cables should not be less than 12 times the outer diameter of the cable.

There are three types of shielding materials: round copper wire, copper strip, and aluminum strip/plastic composite strip. Shielding pairs have good insulation performance, and if there is a potential difference between shielding pairs during cable use, it will not affect the transmission quality of the signalApplication of computer cable products: This product is suitable for signal transmission and detection instruments and meters in power generation, metallurgy, petrochemical and other industrial and mining enterprise distribution systems, electronic computer systems, automation systems with rated voltage of 450/750V and below or DC 1000V and below.

DJYVP computer shielded cable 2 * 1.5mm voltage 300/500V

Adopting K-type B-class low-density polyethylene with antioxidant properties. Polyethylene has high insulation resistance, good voltage resistance, low dielectric constant, and minimal temperature and frequency effects on dielectric loss. It not only meets the requirements of transmission performance, but also ensures the service life of cables.

In order to reduce mutual crosstalk and external interference between circuits, the cable adopts a shielding structure. The shielding requirements for cables are based on different occasions, using methods such as twisted pair combination shielding, total shielding of twisted pair cables, and total shielding after twisted pair combination shielding. Shielding materials include round copper wires, and communication between PCs and smart devices often relies on DJYPVP, Ethernet, and other methods, mainly depending on the interface specifications of the device. But DJYPVP can only represent the physical medium layer and link layer of communication. If bidirectional access to data is to be achieved, communication applications must be written by oneself. However, most of these programs cannot comply with ISO/OSI specifications and can only achieve relatively single functions, suitable for a single device type. The program does not have universality. In a device network composed of DJYPVP or DJYPV devices, if the number of devices exceeds 2, RS485 must be used as the communication medium. The communication between devices in the DJYPVP and DJYVP networks can only be achieved through a "master" device relay, which is usually a PC. In this type of device network, only one master device is allowed to exist, and the rest are all slave devices. Fieldbus technology is based on the ISO/OSI model and has a complete software support system that can solve problems such as bus control, conflict detection, and link maintenance.Low smoke halogen-free flame-retardant computer cable

Purpose: This cable has low voltage capacitance and low inductance, as well as good shielding and anti-interference performance, making its explosion-proof performance superior to general computer cables and control cables. It is suitable for use as a transmission line in distributed systems and automation detection and control circuits with explosion-proof requirements, such as low smoke, halogen-free, and flame-retardant circuits
