The mining cable series price formula is as follows: Copper weight X Copper price calculation: Silk ÷ 2 = 1.25 X 1.25 X 3.14 = Number of squares X Number of X X X X X X X X X X X X X X X X X X X X X X X X X X X X + Y +1 At the time, the processing fee was +10%. The cost of mining cables is calculated as the square X1.83 = the weight of copper x the current price of copper + the price of equipment (weight x 0.4 yuan/kg) = the cost price + 10% of the processing fee cable price = manufacturing material cost + Fixed costs + taxes + operating costs + profits manufacturing material costs = material costs * (1 + material consumption) (material cost is calculated theoretically) The fixed costs vary according to the situation of each company, generally including production wages, management Wages, utilities, repairs, depreciation, rent, and transportation costs increase the life span. The local bending radius of the shearer cable during use is much smaller than the bending radius of the standard cable, and the cable is frequently subjected to excessive bending and stretching for a long period of time. The composite effect of two or more stresses, together with the cross-section of the control core conductor is much smaller than the conductor cross-section of the main cable core of the cable, resulting in a broken core of the control wire core.
1. Increase the flexibility of shearer cables used in coal mines;
2. Increase the relative slippage of the control wire core;
3. Increase the strength of shearer cable conductors for coal mines;
4, the conductor from the original bundle of twisted structure was changed to a normal twisted, so that it can increase its bending performance, and then wire braided outside the conductor, and increase its strength;
5, the control core can use tinned copper wire and wire braid weaving, is also a good method.
First, the name of the mining cable consists of eight parts:
The first part is series code M, the first prefix of the pinyin of coal.
The second part is the use of characteristic codes, reflecting the occasions used for mining cables. The meanings of the letters are as follows: C, for coal mining machine; D, for low-temperature environment; M, cap lamp; Y, for coal mining equipment (moving); Z, for electric drilling.
The third part is the structural feature code, indicating the structural characteristics of the mining cable. The meanings of the letters are as follows: B, weaving strengthening; J, with monitoring core; P, non-metallic shielding; PT, metal shielding; Q, lightweight;
The fourth part is the material feature code, E is used to indicate that the insulation or sheath is made of elastomer material. This part is omitted when rubber and insulation are used. E, elastomer material.
The fifth part is rated voltage U0/U(KV).
The sixth part is the representation of the number of power cores * nominal cross-sectional area. The two are connected by a multiplication sign and the unit is square millimeters.
The seventh part is the representation of the number of ground cores* nominal cross-sectional area. The two are connected by a multiplication sign and the unit is square millimeters.
The eighth part is the representation of the number of auxiliary cores * nominal cross-sectional area. The two are connected by a multiplication sign and the unit is square millimeters.
The fourth part and the fifth part are connected with "-"; the sixth part, the seventh part and the eighth part are connected with "+".
The company solemnly declares:
1, signed a product quality assurance book, promise - never failed to leave the factory.
2. Two years of product quality tracking service, and record customer service records for 20 years.
