How to choose Distribution Transformer?

The Key Selection points of Oil-Immersed Distribution Transformer . Load Properties of Distribution Transformer: 1) When there are a large number of primary or secondary loads, it is advisable to install two or more transformers. When one transformer is disconnected, the capacity of the remaining transformers can meet the demand of primary and secondary loads. First, the secondary loads should be concentrated as far as possible and should not be too dispersed. 2) When seasonal load capacity is large, special transformer should be installed. For example, in large civil buildings, the load of air conditioning refrigerators, heating electricity and heat, etc. 3) When the concentrated load is large, special transformer should be installed. Such as large heating equipment, large X-ray machine, electric arc furnace, etc. 4) When the lighting load is large or the power and lighting use common transformer seriously affects the lighting quality and lamp life, special lighting tra

What is Die Casting Machine - Types of Die Casting Machine | KYLT Industrial

What is Die Casting Machine - Die Casting Machine Types, Die-casting mould & Die casting parts Die casting process , by injecting molten metal under pressure into die casting dies or molds. Die casting mould consists two halves: fixed die half, movable die half. Metal shapes are formed by mold cavity. When mold open, we can obtain the cast metal parts. The machine which used to finish the die casting process is named Die casting machine. It has two mechanism: Cold chamber & Hot Chamber . Here, we will introduce the equipment for this process, what is die casting machine, die casting machine types, their mechanism & features, how to choose suitable die casting machine. What is Die Casting Machine? Die casting machine is one kind non-ferrous metal products making mechinery. It is a metal casting process, by inject molten metal into the mold cavity, the shape of the die casting parts will be formed when the metal is cool and solidified. This manufacturing method can
