3优Mining Cable
Mining cables are wires and cables used in the mining industry and are very important in coal mine shafts. Mining cables are used in the coal mining industry to connect machines and equipment such as coal miners, transporters and basic lighting and communication. Due to the harsh working environment of mining cables, the excessive accumulation of coal mines can easily cause explosions, so the safety requirements for cables are very high.
Mining cable is a common name for coal mine cable, mining cable are insulated wires, all should have been through the safety standard of China's mining anti-commodity safety mark management centre awarded the mining anti-commodity safety mark qualification certificate. Mining cable refers to the coal mining industry with the use of ground equipment and underground equipment with wire and cable products. Including coal mining machine, conveyor, communication, lighting and signalling equipment with cables, as well as electric drill cables, cap lamp wire and underground mobile substation power cables.

Mining Cables Use characteristics
Application
1. Wide range of applications, of which the main use is the surface and underground equipment in the mining industry, involving mining electric drill cables, communication and lighting equipment cables, mining and transport cables, mining lamp cables and underground mobile substation power supply cables;
2. Due to the harsh working environment of mining cables, the use of the environment is extremely complex, and the excessive accumulation of coal dust can easily cause explosions;
3. When using mining cables, they need to be moved, bent and twisted frequently. So the wire is soft, structurally stable, not easy to kink, etc. And has a certain degree of wear resistance.
Mining cable series price formula is as follows: the weight of copper X copper price calculation: wire by ÷ 2 = 1.25X1.25X3.14 = square number of roots X silk X0.89X the then copper price +10% of the processing fee.
Mining cable cost price calculation Square X1.83 = the weight of copper X the then copper price + armouring price (weight X 0.4 yuan / kg) = cost price + 10% of the processing fee The price of the cable = the cost of manufacturing materials + fixed costs + taxes + business expenses + profit Manufacturing material costs = material costs * (1 + material consumption) (material costs that is, the theoretical calculated value) Fixed costs vary according to the individual Fixed costs vary according to each company, and generally include production wages, management wages, utilities, repairs, depreciation, rent, and transport costs.
Classification and Use
For coal mine underground use of rubber cables, plastic cables and communication cables MT818.1 ~ 818.14 a - 2009 made specific provisions, in accordance with the provisions of the T818 standard who will be flame retardant cables for coal mines are divided into coal mines with a mobile class of flame retardant flexible cables, coal mines with a rated voltage of 10kW and the following copper-core fixed-laying flame retardant power cables and coal and fire-retardant communication cables of three categories.
Mining cables can be divided into rubber cables, armoured cables and plastic cables according to the structure of the three kinds of cables, according to the use can be divided into signal communication cables, control cables and power cables, according to the voltage level can be divided into low-voltage cables, high-voltage cables and kilovolt cable, according to the cable core material can be divided into copper-core cables and aluminium-core cables.
Structure type
Mining cable can be divided into rubber cable, armoured cable and plastic cable according to the structure of three kinds.
The so-called armoured cable is a steel wire or steel belt to armour the cable. Due to the strong tensile strength of steel wire or steel belt, steel wire armoured cables are mostly used in vertical shaft or sharp inclined tunnel; while steel belt armoured cables are mostly used in horizontal tunnel or slow inclined tunnel. The biggest advantage is the high insulation strength, suitable for high-voltage cable, in the underground mostly used for fixed equipment and semi-fixed equipment armoured cable power supply.
Rubber cable is divided into ordinary rubber cable, flame retardant rubber cable and shielded rubber cable. For the power supply of underground mobile equipment, more flexible, able to bend the rubber cable. Rubber cables are mainly used to pregnant to the mining area mobile equipment power supply.
The main structure of the plastic cable and the rubber cable is basically the same. Only its core insulation and outer sheath are made of plastic (polyvinyl chloride or cross-linked polyethylene), the advantages are: allow high working temperature, good insulation, corrosion-resistant sheath, taught to set the drop is not limited. If the cable is armoured externally, it is used under the same conditions as armoured cables; if it is not armoured externally, it is used under the same conditions as rubber-sleeved cables. Therefore, in the conditions permit, should try to use plastic cables.
1. Mining cable is the abbreviation of coal mine cable, mining cable are flame retardant cable, should be issued by the National Mining Product Safety Mark Centre after the safety standard mining product safety mark certificate, mining cable has the following six models, YQ type.
2, that is, light general-purpose rubber cables, connecting AC voltage 250V and the following light mobile electrical equipment, YQW type.
3, that is, outdoor light general-purpose rubber cables, can be connected to both AC voltage 250V and the following light mobile electrical equipment, but also has the weather resistance and a certain degree of oil resistance.
4.YZ type, that is, medium-sized general-purpose rubber cables, can be connected to AC voltage 500V and below various mobile electrical equipment, YZW type.
5. that is, outdoor medium-sized general-purpose rubber cable, can be connected to AC voltage 500V and below a variety of mobile electrical equipment, heavy-duty general-purpose rubber cable YC type, that is, heavy-duty general-purpose rubber cable, can be connected to AC voltage 500V and below a variety of mobile electrical equipment.
6. and can withstand large mechanical, YCW type, that is, outdoor heavy-duty general-purpose rubber cables, can be connected to the AC voltage 500V and below a variety of mobile electrical equipment, with weather resistance and a certain degree of oil resistance.
There are many models of mining cable, mining power cable, mining control cable, coal mining machine cable and mining rubber mobile flexible cable, different models of mining cable service life is not the same.
Mining power cable (MYV, mining control cable (MKWVMKYJV) = general fixed laying, the service life is generally very long, at least 10 years. Coal mining cable, its service life is not very high, the quality of a good point in half a year to a year, the quality of the second point of 7 days to 3 months, the mine in order to be safe, generally a cable used to a certain time will have to change. Mining mobile flexible cable life is not very long (MYPMYPTJ), more than one year.
Mineral cable and ordinary cable difference
1. Mineral cable structure is more complex
2. Higher requirements for safety
Mining cable and flame retardant cable difference
Mining cable is the abbreviation of coal mine cable, mining cable are flame retardant cables, all should be issued by the safety mark centre of the safety mark of mining products through the safety standard national mining products.U-type (M-type) rubber cables for coal mines.
Flame retardant cable, refers to the specified test conditions, the specimen is burning, after the withdrawal of the test fire source, the spread of the flame is only within the limits, the residual flame or residual burning in the limited time to extinguish the cable.
