Shandong Usage: Industry. According to an old rule of thumb within the transformer industry, the production cost optimum lies somewhere around a ratio of steel to copper usage of 2:1.However, it is a fairly flat optimum and, of course, varies with the price ratio of steel to copper. Independently of this, it should be taken into consideration that the operating properties of the transformer also vary when the shares are varied, especially with respect to losses:Holding the current densities in the windings and the magnetic flux density in the core constant, the loss per kilogram of copper or steel, respectively, will be more or less constant.

Guangdong It is, however, important from the point of view of the manufacturer that the It is also possible to vary the ratio of copper to steel quantities.

Locating the transformers near the loads may lead to savings in cable costs and reduced electrical losses.Oil Type transformers may require periodic sampling of the oil and more exhaustive maintenance procedures.However, though dry type transformers are advantageous, they are limited by size and voltage rating. This effect is better in less efficient machines.Please note that, when the price of both active materials (magnetic steel and winding material) increases in similar proportion, the optimisation brings only marginal savings in manufacturing cost, when the same loss levels are specified.

Oil Type transformers are considered a potential fire and safety hazard. Watch.

Henan A transformer is a passive electrical device that transfers electrical energy from one electrical circuit to another, or multiple circuits.A varying current in any one coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force across any other coils wound around the same core. Shandong So manufacturers rather prefer to agree certain capitalisation based formula when optimisation of transformer may bring some savings in manufacturing cost.Today, the cost active materials in an average distribution transformer represents about 50% of the transformer total price; taking all materials into account increases this to 70% of the total price.Efficiency improvement today by reducing no-load losses adds to the cost by about 0.3% to 0.7% for 1% loss reduction in the area of moderate losses (between A’ and C’ level) and from 0.7% (close to C’) to 1.4% in area of very low losses (more than 20% below C’).

Thereby a transformer designed according to this philosophy, but with more iron and less copper, tends to have higher iron losses, and one with more copper and less iron will have higher The progress in the scope of calculation techniques allows for optimisation to get a precise model of the transformer geometry, taking into account the actual core cross-section and the location of windings. See similar items. Golden Triangle Electric Power Technology Co., Ltd. Oil Type transformers require the development and maintenance of reliable fire safety and extinction proceduresDry Type Transformers can be located closer to the load unlike oil transformers which require special location and civil construction for safety reasons. Commodity prices have gone up for the last few years and have outweighed the cost-reducing effect of optimisation and technological improvements.The cost of active materials in typical transformers increased by more than 50% between the years 2003 and 2007.
