( Industry news] Buy cable never cheated, teach you accounting X copper cable of this bjdianlan P copper weight calculation: present size =. X。 X。 The number X = square number X silk. When prices + X % of the processing fee. Cabtyre cable cost price calculation formula of the square X. Copper = X when the weight of the copper price + the price of rubber ( The weight of the X. Yuan/kg) = cost price + % of the processing charge cable price = production material cost plus fixed fee + tax + service charge + profit made the cost of materials = material cost * ( + material consumption) ( The cost of materials is the theoretical calculated values) Fixed fee according to each company's situation is different, generally including the production of the salary, salary management, utilities, repair cost, depreciation cost, rent and transportation cost load flow calculation formula for estimating formula by two point five to 9, reduce YiShun number go up. 35 by three point five, both groups decrease point five. Conditions change and conversion, high temperature copper upgrade ninety percent. Wear tube number 234, 234 fold full flow. Note: this section formula of all kinds of insulated wire ( Rubber and plastic insulated wire) The carrying capacity of ( Safety current) Not directly points out, but 'section multiplied by a certain ratio', by mental arithmetic. It can be seen: multiples and decreases with the cross section. Mm 'and under all kinds of section aluminum core insulation wire, its carrying capacity is about section several times. ( A) 。 From mm and above 'carrying capacity and the section of the wire number multiples of relationship is down to the top of line number, ratio of successive minus l, namely, *, *, *, *, *. 35 by three point five, both groups decrease point five. ( A) 。 . Namely, mm 'carrying capacity of cross section of the wire several times; Times, and so forth. Conditions change and conversion, high temperature copper upgrade ninety percent. 'Conditions change and conversion, high temperature ninety percent copper upgrade'. The above formula is the aluminum core insulation wire, Ming fu in ℃ ambient temperature conditions. If aluminum core insulation wire Ming fu in the environment temperature is higher than ℃ region for a long time, wire carrying capacity according to the above formula calculation method to calculate, then ninety percent discount; When using copper rather than aluminum wire insulation wire, its carrying capacity than the same specification aluminium wire are slightly larger, according to the above formula method to calculate than aluminium wire increase the carrying capacity of a line number. Such as mm 'copper wire carrying capacity, can be calculated at the mm aluminium wire. Wear tube number 234, 234 fold full flow. Wear tube number 234, 234 fold full flow 'wear pipe laying two, three, four wires, its carrying capacity is an electrical mouth should calculate respectively carrying capacity ( Single installation) %, %, %.
