Rubber sheathed cable concept and classification

First, the concept of rubber 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 the result of hinges inside the molecular chain. 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 general-purpose type, electric welding machine, electric power, marine use, mining, wind energy, nuclear energy, etc., among which are widely used. The mobile general purpose rubber sheathed cables and mine cables are used. This lecture mainly discusses the combination of these two types of cables.

1. The mobile universal rubber sheathed cable is suitable for household appliances, power tools and various mobile devices with AC rated voltage of 450/750v and below. The main models include 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, which is used for light moving edge equipment and tools. It has excellent flexibility and generally does not bear external force.

YZ medium model: The full name of the model is the mobile universal medium-sized rubber sheathed flexible cable, which is used for various mobile devices and tools, has sufficient flexibility, is easy to move, bends, and can withstand general mechanical external forces.

YC Heavy: The full name of the model is the mobile universal heavy-duty rubber sheathed flexible cable, which is used in various mobile electrical equipment, can withstand large external mechanical 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.

1). Named category mining cable name is composed of eight parts of the first part of the series code with M; the second part uses the characteristics of the code; the third part of the structural characteristics of the code; the fourth part of the material characteristics code (plus -); Part 5: Rated voltage U0/U(kv); Part 6: Number of power lines × Nominal cross-sectional area; Section 7: Number of ground lines × Nominal cross-sectional area; Section 8: Number of auxiliary lines × Nominal cross-sectional area .
