Cables are divided into Multi core Cable and single-core cables according to the number of cores. Cables with two or more cores are called Multi core Cables. Common Multi core Cables include two-core, three-core, four-core, five-core, 3+1 core, 3+2 core, 4+1 core, etc. The number of cores of the control cable can reach 61 cores. Most of the cables currently used in the market are Multi core Cables, so the models of Multi core Cables are also varied. Here TST CABLES lists some common models of Multi core Cables. I hope there is the information you want in it. If not, you can email us for consultation.
Number of cores in Multi core Cable
Two cores are used to control an electrical appliance. One is the live wire and the other is the neutral wire. The switch is connected in series in the middle of the live wire to turn on or off the power supply;
Three cores are generally used for 380V power lines. One of them is the neutral wire and the other two are the live wires. The electrical appliance and the power supply are controlled by three gate switches or magnetic starters. They are mostly used for three-phase motors or welding machines;
Four cores are generally used for household power lines. One is connected to the neutral wire and the other three are connected to the A, B, and C live wires of the transformer. The A, B, and C live wires have roughly the same power at the end, so that the output power of the transformer is stable;
Five cores are generally used in a small space with many electrical appliances. In this way, it can control five electrical appliances. The multi-connection switch is connected in series to the five live wires, and the five electrical appliances share a neutral wire.

Classification of Multi core Cables
- Rubber sheathed cable
Rubber sheathed cable is a soft and movable cable with multiple strands of fine copper wire as conductor, covered with rubber insulation and rubber sheath. Models include YC cable, YCW cable (rubber sheathed cable is divided into heavy rubber sheathed soft cable); YZ cable, YZW cable (medium rubber sheathed soft cable); YQ cable, YQW cable (light rubber sheathed soft cable); JHS cable, JHSP cable (waterproof rubber sheathed soft cable); YH cable, YHF cable (electric welding machine cable) and YHD cable tinned power connection line for field use.
- Mineral insulated cable
Mineral insulated cable (Mineral insulated cable) is a cable with a copper sheath wrapped around the copper conductor core wire and magnesium oxide powder as an inorganic insulating material to isolate the conductor and the sheath. The outermost layer can be selected as required. Appropriate protective sheath. There are only six types of national standard rigid cables: BTTQ, BTTVQ, WD-BTTYQ for light load 500V, and BTTZ, BTTVZ, WD-BTTYZ for heavy load 750V; national standard flexible cable models: RTTZ, RTTYZ, RTTVZ, voltage level: 0.6/1kV or 450/750V; the remaining flexible cable models are named by each manufacturer, and the common ones are BTWTZ, GAN-BTGYZ, BTLY, NG-A, etc., totaling more than a dozen.
- Computer cable
Computer cable is a cable for electrical equipment. According to the use requirements of different environments and equipment, the cable insulation can be made of polyethylene, polyvinyl chloride, cross-linked polyethylene, fluoroplastics, silicone rubber and other materials. The main signals are DJYPV, DJYVP, DJYPVP, DJYP2V, DJYVP2, DJYP2VP2, DJYP3V, DJYVP3, DJYP3VP3, DJYPVR, DJYVPR, DJYPVPR, DJYPVPR, DJYVP2R, DJYP2VP2R, DJYP3VR, DJYVP3R, etc.
- Flat cable
Flat cable is a cable with a flat shape, as shown in the figure above. Flat cable models include TVVB, TVVBP, YVFB, YFFB, RVVB, YGCB, etc.
- Drag chain cables
Drag chain cable is a cable installed in a drag chain box. It is a highly flexible special cable that moves back and forth with the drag chain and is not easily worn. Models include TRVV, TRVVP, TRVVPS, TRVVY, PUR-TRVV, etc.
- Mining Cable
Mining cable is the abbreviation of coal mine cable. All mining cables are flame-retardant cables and should be issued with the Mining Product Safety Mark Certificate by the National Mining Product Safety Mark Center. Mining cable models include mc cable, mcp cable, mz cable, mzp cable, myq cable, my cable, mcptj cable, myptj cable, mvv cable, mkvv cable, myjv cable, mkyjv cable, mhyv cable, ugf cable, etc.
Multi core Cable selection guide
Multi core Cable have been widely used in many industrial, commercial and civil fields because of their ability to transmit multiple signals or power at the same time. The correct selection of Multi core Cables is essential to ensure the reliable operation of the system. The following is a detailed Multi core Cable selection guide from TST CABLES to help you make wise Multi core Cable selection decisions.
- Determine application requirements
Use environment: indoor or outdoor? Are there special environmental factors (such as high temperature, humidity, corrosive gases, etc.)?
Cable path: Does it need to bend, twist, or move frequently?
Installation space: Are there any space restrictions? - Understand cable parameters
Number of cores: Determine the number of cores required based on system requirements.
Conductor material: Copper or aluminum conductor, copper conductor generally has better conductivity.
Conductor cross-sectional area: Calculate the required conductor cross-sectional area based on current load and voltage drop.
Insulation material: Select appropriate insulation material (such as PVC, XLPE, etc.) according to the use environment.
Sheath material: Consider the external protection requirements of the cable (such as PVC, rubber, etc.).
Shielding layer: Is a shielding layer required to reduce electromagnetic interference (EMI)? - Evaluate performance indicators
Electrical performance: Including parameters such as resistance, capacitance, and inductance.
Mechanical properties: Such as bending radius, tensile strength, etc.
Environmental adaptability: Including temperature resistance range, chemical resistance, etc.
Fire resistance: Is low smoke halogen-free (LSOH) or flame retardant performance required? - Consider installation and maintenance

Field testing: Test the performance of the cable in the actual application environment. - Installation Instructions
Installation Manual: Follow the installation manual provided by the manufacturer for installation.
Professional Training: For complex installations, consider receiving training or guidance from professionals. - Regular Maintenance
Maintenance Plan: Develop a regular inspection and maintenance plan.
Troubleshooting: Establish a troubleshooting process to deal with possible problems.
Choosing the right Multi core Cable is essential to ensure the stable operation of the system. By comprehensively considering factors such as application requirements, performance indicators, installation and maintenance requirements, and cost-effectiveness, you can find the cable solution that best suits you. The right selection can not only improve the reliability of the system, but also save overall costs and ensure the long-term return on investment of the enterprise.
The above are some of the models of TST cables’ customized Multi core Cables, which only account for a small part of the Multi core Cable models. I will not introduce more Multi core Cables here one by one, and I can’t introduce them all, because there are too many types. As for the specifications of Multi core Cables, the specifications are the size of the cable. Each model of cable has many specifications, more than the models. I hope the above information is helpful to you!
