Analysis: the definition of rubber sleeve cable

As the name suggests, rubber thermosetting elastomers based on various rubbers or equivalent properties are rubber-insulated and sheathed. The so-called thermosetting plastic elastomers are the ones that have been heated and formed and cured. The shape of the rubber is due to the internal hinges of the molecular chains. Stabilization (usually called vulcanization or cross-linking in this process) reheats it again and does not allow it to reach viscous flow again, and it is then processed again to shape the elastomer.

Because of its unique softness, rubber jacket cables are often used in mobile electrical equipment.

Second, the classification of rubber cable

Because of its unique mechanical properties and physical properties, rubber sheathed cables are used in many fields. Therefore, there are many types of rubber cables, such as: universal type, electric welding machine, electric power, marine use, mining, wind energy, nuclear energy, etc. It is a mobile universal rubber sheath cable and mining cable.

1, mobile universal rubber sleeve cable

Suitable for household appliances, power tools and all kinds of mobile equipment with AC rated voltage of 450/750v and below. The main models are YQ (H03RT) light, YZ (H05RNH05RR) medium, and YC (H07RN) heavy. (The part outside the parentheses is the reference standard GB5013.4, and the reference part within the parentheses is VDE 0282.4.) The voltage of the light mobile general purpose rubber sheath cable is generally 220v, which is mainly used for everyday electrical equipment installations. The voltage rating of medium and heavy-duty mobile general-purpose rubber cable is generally up to 380V, which is mainly used for industrial electrical equipment installations.

YQ Light: The full name of the model is the mobile universal light rubber sheathed flexible cable. It is used for light moving edge equipment and tools. It has excellent flexibility and generally does not withstand external forces.

YZ Medium: The full name of the model is the mobile universal medium-sized rubber sheathed flexible cable used for various mobile devices and tools. It is flexible enough to move, bend, and withstand general mechanical forces.

YC Heavy: The full name of the model is the mobile universal heavy-duty rubber sheathed flexible cable . It is used in various mobile electrical equipments. It can withstand large mechanical external forces and can withstand its own drag force. The sheath should have high elasticity and The mechanical strength should also have a certain degree of flexibility to ensure movement and bending.

2. Mining cables (quoted from the standard: MT818-2009)

The name of the mining cable.

The name of the mining cable is composed of eight parts. The first part of the serial number is denoted by M; the second part is the characteristic code; the third part is the structural feature code; the fourth part is the material feature code (plus-); /U(kv); Section 6. Number of power line cores x nominal cross-sectional area; Section 7 Number of ground lines cores x nominal cross-sectional area; Section 8 Number of auxiliary lines × Nominal cross-sectional area.
