Model of mobile rubber sheathed flexible cable

Mine cable is a general term for flame retardant cables for coal mines

Working voltage of mobile flexible cables for coal mines:

The rated current is indicated by U0/U, and the enterprise is kV. U0 indicates the effective value of the voltage between any main insulated conductor and the “ground” (metal material shielded, metal material sheath or surrounding material); U is the middle of a multi-core cable or a single-core cable system software. The effective value of the voltage.

In an AC system, the rated voltage of the cable should be at least equal to the nominal voltage of the system to which the cable is applied. This standard is applicable to both U0 and U values.

Naming standards for mobile flexible cables:

The name of the mobile flexible cable is composed of seven parts: among them: the first, second, third, fourth, and fifth parts constitute the model specifications of the cable; the sixth, seventh, and eighth parts The specifications and models that make up the cable.

The first part: use English capital letter M to indicate the serial product number of cables for coal mines.

The second part: application application feature number, reflecting the place where the cable is applied,

C: For coal mining machine, D, for ultra-low temperature natural environment, M: for cap lamp, Y: for coal mining machinery and equipment (mobile), Z: for electric drill.

The third part: the characteristic number of the cable, B: manual braided lifting; J monitoring or auxiliary copper core cable; P: non-metallic material shielded; PT: metal material shielded; Q: light-shaped; R: wrapping and lifting.

The fourth part is the characteristic number of the raw material. Use E to indicate that the insulation layer or the sheath is made of polyurethane elastomer. This part is omitted when vulcanized rubber is used for both the insulating layer and the wire sheath. E, polyurethane elastomer raw materials

The fifth part: Indicate the rated current U0/U, the enterprise is KV (kV).

Part 6: Indicate the number of cores of the driving force * tolerance cross section, and the two are connected by “×”. Tolerance cross-section enterprise is square millimeter (mm2)

Part 7: Indicate the number of grounding wire cores*tolerable cross-section, and the two are connected by “×”. The tolerance cross-section enterprise is square millimeter (mm2).

The eighth part: Indicate the number of bisector cores*tolerable cross section, with “×” between them

Join. The tolerance cross-section enterprise is cubic millimeter (mm2).

The fourth part and the fifth part are connected by “-”; the sixth part, the seventh part, and the eighth part are connected by a “+”.

Mobile flexible cable core specifications: 1, 1.5, 2.5, 4, 6, 10, 16, 25, 35, 50, 70, 95, 120, 150, 185, 240, 300, 400,

The use of ACSR conductor 


Rubber sheathed cables are widely used in various electrical equipment, such as portable power cords for household appliances, electrical machinery, electrical equipment and appliances, and can be used in indoor or outdoor environmental conditions. According to the mechanical external force of the cable, the product structure is divided into three types: light, medium and heavy, and there is also an appropriate connection in the section. Generally, light-duty rubber-sheathed cables are used in household electrical appliances and small electric equipment, requiring softness, lightness, and good bending performance. In addition to industrial use, medium-duty rubber-sheathed cables are widely used in agricultural electrification, and heavy-duty cables are used in port machinery, searchlights, Large-scale hydraulic irrigation and drainage stations in the family business. This type of product has good versatility, complete series specifications, good performance and stability.

Waterproof rubber sheathed cables and AAC conductor for submersible pumps are mainly used for submersible motors. The model is JHS, JHSB.

For cables for radio devices, currently two types of acsr conductor (one shielded and one unshielded) are mainly produced, which can basically meet the requirements. The model is WYHD, WYHDP.

Photographic cable products, in line with the development of new light sources, have a small structure and good performance, while meeting the needs of indoor and outdoor work, and gradually replace some old products with heavy weight and poor heat resistance.

Rubber cable model

Rubber sheathed cables are divided into heavy rubber sheathed flexible cables (YC cables, YCW cables), medium-sized rubber sheathed flexible cables (YZ cables, YZW cables), light rubber sheathed flexible cables (YQ cables, YQW cables), and waterproof rubber sheathed flexible cables ( JHS cable, JHSB cable), welding machine cable (YH cable, YHF cable) and YHD cable are tin-plated power cables for field use.
