Introduction to various types of cables: General rubber sheathed cables
Universal rubber sheathed cable is a flexible cable with rubber insulation and rubber sheath structure, which has characteristics such as oil resistance, wear resistance, and bending resistance. It is widely used in mobile power supply, electric tools, mining equipment and other occasions that require frequent dragging or outdoor use. Its core advantages are good flexibility and strong environmental adaptability, suitable for power transmission under complex working conditions.
- Conductor: Stranded multiple strands of fine copper wire (Class 5 standard) to ensure flexibility.
- Insulation layer: natural rubber, chloroprene rubber (CR) or ethylene propylene rubber (EPDM), excellent weather resistance.
- Sheath: Black or orange rubber, resistant to mechanical damage and ultraviolet (UV) radiation.
- Voltage level: 300/500V (low voltage) or 450/750V (medium low voltage).
| Characteristic | Advantage |
|---|---|
| Flexibility | Can withstand more than 100000 bends (such as YC cables) |
| Oil resistivity | Chloroprene rubber sheath resistant to engine oil and diesel (such as YCW type) |
| Weather resistance | -Stable operation in an environment of 40 ℃~70 ℃ (ordinary PVC wire only works at -15 ℃~70 ℃) |
| Tensile strength | Heavy duty model (YC) with steel wire reinforcement layer, tensile strength ≥ 10kN |

| 1. General rubber sheathed cables have a wide range of applications, suitable for general occasions that require mobile connections for various electrical equipment, including electrical mobile equipment connections used in various sectors of industry and agriculture. 2. According to the cross-sectional size of the cable and its ability to withstand mechanical external forces, it can be classified into three types: light, medium, and heavy. These three types of products all have requirements for softness and flexibility, but lightweight cables have higher requirements for softness and should be lightweight, small in size, and unable to withstand strong mechanical external forces; Medium sized cables have a certain degree of flexibility and can withstand considerable mechanical external forces; Heavy duty cables have high mechanical strength. 3. The cable sheath should be tight, sturdy, and have a certain degree of roundness. YQW, YZW, YCW cables are suitable for outdoor use (such as searchlights, agricultural plows, etc.) and should have good resistance to sunlight aging. | 1. Conductive wire core: Made of copper flexible wire bundle twisted, with a flexible structure and a large cross-sectional surface that allows for paper wrapping to improve bending performance. 2. The insulation is made of natural styrene butadiene rubber, which has good aging performance. 3. The rubber of outdoor products is made of chloroprene rubber or a mixed rubber formula mainly composed of chloroprene rubber. |
- Mining equipment: YC 3 × 25+1 × 16mm² cable supplies power to the rock drill.
- Port crane: YCW cable is resistant to seawater corrosion and mechanical drag.
- Construction site mobile distribution box: YC 3 × 6+1 × 4mm² cable temporary power supply.
- Vibration rod: YZ cable is resistant to frequent bending.
- Agricultural irrigation pump: YZW cable is sun and rain resistant.
- Welding machine: YH 50mm² cable for high current transmission.
Mechanical strength: Light (YQ) → Household, Heavy (YC) → Mining/Construction Sites.
Environmental adaptability: Choose YCW for oily environments and YZW (UV resistant) for outdoor use.
Current load:
| Cross sectional area (mm²) | Current carrying capacity (A) |
|---|---|
| 1.5 | 16 |
| 6 | 42 |
| 25 | 108 |
- Bending radius: ≥ 6 times the outer diameter of the cable (to prevent internal damage).
- Tensile protection: Heavy cables require pulleys or cable reels for retraction and loading.
- Joint treatment: Seal with waterproof tape or heat shrink tubing (outdoor scene).
- Material upgrade: Synthetic rubber (such as CPE) replaces natural rubber to extend its lifespan.
- Environmental requirements: The demand for halogen-free sheaths (LSZH) is increasing due to the EU REACH regulation.
- Intelligent monitoring: Rubber sheathed cable with integrated temperature sensor (for industrial IoT applications).
6、 Summary: Universal rubber sheathed cables are the "durable blood vessels" for mobile power supply scenarios, and selection should focus on mechanical strength, environmental tolerance, and current carrying capacity. With the popularization of new energy equipment and automation machinery, rubber sheathed cables with high flexibility, toughness, oil resistance, and flame retardancy will become mainstream.
