Pls what kind of cable is IJYJPVRP

Computer-shielded distributed DCS intrinsically safe cables.

YJV can be understood in the cable as follows: YJ is cross-linked polyethylene insulation; And V stands for PVC sheath. Therefore, the full name of YJV is XLPE insulated PVC sheathed power cable.

YJV is also divided into different models, and the general purpose is different for different models. YJV cable is XLPE insulated polyethylene sheathed cable. Its product standard is GB12706, 3---91, and its use temperature should not be lower than 0 degrees.

It can withstand mechanical external force, but cannot withstand the occasion of large tensile force.

Features of YJV cables

YJY cable has a simple structure, moderate hardness and softness, and is convenient for transportation, but it is not compressive, so it should be paid attention to when storing or transporting.

The polyethylene raw material used in YJY cable is higher than that of PVC material, which creates the high cost of YJY cable, but the temperature resistance level of XLPE cable is 90 degrees, and the working temperature of PVC cable is only 70 degrees.

According to the requirements of some users, YJY power cable can produce flame-retardant (ZB), fire-resistant (NH), low-smoke and low-halogen (WDZ) and other high-demand cables, which have high safety and practicability, and strong environmental performance.

1. The meaning of the code is different: YJ, cross-linked polyethylene insulation. e, poly such as Zhiyun olefin sheath. v, PVC protective mindset.

2. The cable structure is different: the sheath material of YJV is polyvinyl chloride. YJE's jacket is made of polyolefin.

3. The scope of application is different: YJV, laid indoors, tunnels, cable trenches and pipelines, can also be buried in the loose soil of slag beams, and the cable can withstand a certain radiation traction. YJE said: Basement, subway fire fighting places, flame retardant general.

What type of cable is ZB-IC-JYPVRP?

Hello, dear <>

It is a shielded cable that is mainly used to transmit audio, ** and control signals. It consists of multiple insulated conductors, each encased in a shielding layer to reduce interference and noise. A layer of PVC sheath is also wrapped in the outer layer of the cable to improve the durability and water resistance of the cable.

Cables are commonly used in audio equipment, stage lighting, and security systems to transmit high-quality audio and alarm signals, as well as control signals such as RS485 and DMX512. 3.In addition to ZB-IC-JYPVRP cables, there are many other types of liquid shielded cables, such as RG6, RG58, RG59, RG11 and other troublesome cables.

Each cable has its specific uses and benefits. Choosing the right cable type ensures good signal transmission and equipment performance.

YJV what kind of cable, many people will not know much, in fact, there are so many kinds of cables on the market, not this aspect of the personnel, it is difficult to understand, but we still have to do a certain understanding, in the future to use it will be clear and not deceived, now to find out!

First of all, I will introduce what YJV means, YJV stands for cross-linked polyethylene, V stands for polychlorine, then YJV is cross-linked polyethylene insulated PVC sheathed cable, the scope of use is for power line transmission and distribution with rated voltage of (U0 U), the maximum rated temperature of the cable conductor is 90 °C when used, and the maximum temperature of the cable conductor does not exceed 250 °C when the short circuit (the longest duration does not exceed 5s).

YJV cable laying.

Copper (aluminum) core XLPE is laid indoors, channels and pipes, and can also be buried in loose, insulated PVC sheathed power cable soil, which cannot withstand external force.

YJLV22 copper (aluminum) core cross-linked polyethylene is laid underground, which can withstand mechanical external force, but cannot withstand the large tensile force of ethylene insulated steel tape armored PVC sheathed power cable.

YJV cable technical requirements.

1.The maximum rated temperature of the cable conductor is 90°C, and the maximum temperature of the cable conductor in the event of a short circuit (the maximum duration does not exceed 5s).

The temperature does not exceed 250°C.

2.The ambient temperature when laying the cable should not be below 0°C

3.Allowable bending radius when laying: single-core cable is not less than 15 times the outer diameter of the cable; The multi-core cable is not less than 10 times the outer diameter of the cable.

YJV cables are still used in many buildings, so we still have to understand a little, otherwise it will cause certain obstacles when used in the future.

What it means:

YJV stands for alternating polyvinyl chloride;

4*25+1*16 means that the cross-section of 4 (3-phase wire + 1 neutral wire) is 25mm, and the cross-section of 1 ground wire is 16mm.

1. Insulation type: V stands for polyvinyl chloride; x stands for rubber; y for polyethylene; YJ stands for cross-linked polyethylene; z stands for paper.

2. Conductor material: L stands for aluminum; t (omitted) stands for copper.

3. Inner sheath: V stands for PVC sheath; Polyethylene sheath; l Aluminum sheath; Q lead sheath; h rubber sheath; f chloroprene high sheath.

4. Features: D does not drip flow; f-phase-split; CY oil-filled; p-lean oil dry insulation; p-shielding; z DC.

5. Armor layer: 0 none; 2 double steel belts; 3 thin steel wires; 4 thick steel wires.

6. Outer Layer: 0 None; 1. Fiber coat; 2 PVC sheath; 3. Polyethylene sheath.

7. Add zr before the code for flame-retardant cables; For fire-resistant cables, add NH before the code; Add DH before the code for fireproof cables.

Extended Resources:

The types of wires and cables for electrical equipment and power cables are mainly composed of the following seven parts:

1. Category, use code;

2. Conductor code;

3. Insulation layer code.

4, sheath code;

5. Feature code;

6. The code of the armor layer;

7. The code of the outer sheath.

Oil-filled cable model representation method:

1. The oil-filled cable model is composed of the product series code and the code of each part of the cable structure. The product series of self-contained oil-filled cables is codenamed CY. Outer sheath structure.

2. From the inside to the outside, it is represented by the code combination of the reinforcing layer, the armor layer and the outer coat layer. Insulation type, conductor material, inner sheath code and the arrangement of each code.

3. The order and product representation method are the same as those of 35kV and below power cables. For example, cyzq102 220 1 4 means copper core, paper insulation, lead sheath,

4. Self-contained oil-filled cable with radial reinforcement of copper belt, unarmored shielding, PVC sheath, rated voltage of 220kv, single core, and nominal cross-sectional area of 400mm2.

Encyclopedia: Cable model.

The conductor core used in the YJVR cable is a soft structure conductor core composed of multiple thin copper wires twisted in a positive core; The core used in YJV cable is generally a single core formed by a single hard copper wire. 2. Different bending radii:

Due to the different core conductor structures of the two, the allowable bending radius of the YJVR cable when installed is no more than 15 times the outer diameter of the cable for single-core cables and 10 times for multi-core cables; The bending radius of the YJV cable is no more than 20 times the outer diameter of the single source core, and the bending radius of the multi-core is not more than 15 times the outer diameter. 3. Different applicable occasions: YJVR cables are mostly used in some transmission and distribution lines with high requirements for cable flexibility, and there are generally no special requirements for YJV cables.
