In previous years, as the country increased investment in power construction, the transformer market was activated. At present, there are thousands of transformer manufacturers with a certain scale in the country, which can manufacture transformers, transformers, reactors, voltage regulators, and their supporting components, etc. The annual output of various products is close to 140 million KVA. However, at the same time, a large number of companies have flooded into the transformer industry, which has caused the industry's capacity to expand rapidly and some of the drawbacks have begun to appear. In recent years, China's transformer enterprises have been operating in a low-efficiency environment, and the phenomenon of overcapacity is particularly serious. The annual transformer demand in China is about 1.5 billion kVA, while the transformer industry capacity is about 3 billion kVA. Since 2009, the speed of national power construction has slowed down, and the demand for domestic transformers has decreased. In particular, power grid companies adopt centralized tendering methods to purchase transformers. Low-cost bids have led to unprecedented fierce competition among enterprises, and even transformer companies have sacrificed product quality for malicious competition. The situation is chaotic in the market. Current domestic transformer industry specific issues include: 1. The entry threshold of the industry is too low and there is no effective regulatory measures; 2. Serious overcapacity and serious disorderly competition; 3, product quality problems highlighted; 4, lack of new profit growth points; 5. The use of new materials will promote the upgrading and transformation of the industry. If new materials complete the production of large-scale materials and effectively reduce the cost of materials, they will be affected by fatal blows to traditional transformer manufacturers such as silicon steel, and it can be said that they do not possess innovative materials. The serious result of technology is the reshuffle of the industry. In the past, if there were no changes in the industrial development strategy, local transformers would face an impending decline. However, as the industry began to emphasize the concept of energy conservation, the Chinese government has put forward new requirements for the transformer industry, which will stimulate the elimination of backward production capacity.
There are three main types of magnet lamp as following:
Concentrating magnet spotlamp:
Concentrating track lamp is less than the narrow beam Angle range of 20 degrees, can be a place for irradiation or item very conspicuous, but the range is small,light beam light directly, also can become more sharp pair of light spot will become apparent, concentrating track light usually suitable for using in statues, planting flowers, such as art, specific place adorn accent lighting. If used in home space, it is recommended to add soft light lens to modify the light.
Soft light track grille lamp:
Soft light track lamp is 20-40 degrees in the light beam range, compared with the concentrated light track lamp, its light effect will be a little softer, can make the irradiated objects have a strong visual impact, and can not eat the line and texture of the irradiated objects. Soft light track lamp is suitable for wall, painting, photography, general walkway or plane art, etc.
Floodlight magnetic track lamp:
Floodlight type track lamp is more than 50 degrees of wide Angle beam range, belongs to the floodlight source, because the scattering light range is large, can not focus on a single object,but also often together with the background and light source mixed together, more belongs to the atmosphere to create light source, can not guide the visual focus.
