Special remind senphus heating cable users due to the manufacturer of heating cable in recent years, more and more, god fai company with more than ten years experience of heating alloy smelting, and examines the market all the quality of the heating cable, gives the following conclusions: heating cable quality depends on the chosen heating alloy material is the key. The nickel chromium alloy is expensive, high resistivity, short only suitable for the number of meters heating cable, so normal manufacturer choose copper and nickel alloy wire as heat conductor, according to different cable length to choose different type of copper nickel alloy wire. Copper nickel 1 -- copper nickel 19 is yellow because of its high copper content. Copper and nickel 22 - copper nickel 44, because of the high nickel content, is silver white. For the above reasons, many irresponsible manufacturers to expand profit space. When they produce in meters long cable (160-220) when they choose tin plated copper wire or galvanized steel wire or stainless steel wire or aluminum magnesium alloy wire as heat conductor to defraud the user, so there are power attenuation, power shortage phenomenon is not surprising. Since the price of copper and nickel fluctuates too much, when the price of cable is relatively stable, the manufacturers are hurt very much, so there is nothing wrong with double guide single heating cable in the market. The double guide single heating cable is composed of a copper nickel alloy wire and a copper wire. You can see with your eyes a thick silk, a thin filament.
　　Senphus company has its own alloy smelting plant (jiangyin good faith alloy material co., LTD.), so shenghui company has been adhering to double - lead double heating cable. And our smelting copper, copper and nickel alloy wire imported Chile copper, nickel, jinchuan nickel, produced by copper and nickel alloy wire resistance error only Ω 0.01 / m. The power error of the heating cable is only 18W plus or minus 1%.
　　The method of determining the cable is as follows: cutting cable hot end any meter. Measure its resistance. The voltage of 220V is divided by the resistance equal to the power of the cable per meter. But heating cable industry standards: heating cable power error can be negative 10% is 5%, this will cause great trouble to construction unit, short of heating temperature, increase the cost, users complain, etc.
　　The company calls on all the manufacturers in the heating cable industry not to make a small profit for the sake of a small amount of petty profit, shoddy, and cut off the broad prospects of heating cable heating. What we do is people's goods, we must do it with conscience! For the health of the whole industry we should make every heating cable.
