Mining flame-retardant cable prices rose
First, the concept of rubber cables <br> <br> by definition is equivalent to the performance of various rubbers or thermosetting elastomers based rubber insulation and jacketing cables called thermoset elastomers, molding is heat cured after one after Its shape is due to the hinge inside the molecular chain to stabilize the shape (usually this process is called vulcanization or cross-linking,) heating it again does not allow it to reach viscous flow again, and then it will be processed again to form its elasticity. body.
Because of its unique softness, rubber jacket cables are often used in mobile electrical equipment.
Second, rubber cables free <br> <br> rubber cables due to their unique mechanical and physical properties of the products used in many fields, and thus the classification of many, such as: universal, welding, power, marine, Mining, wind energy, nuclear energy, and so on, of which the more widely used are mobile universal rubber sheathed cables and mining cables. 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 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, 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 .
