On March 9, LED manufacturer Ao Liang announced that the company's "LED bulb" replacing traditional quartz bulbs has cut prices by more than 40%, hoping to encourage residents in the port area to switch to such environmentally friendly lamps.
Although the light-emitting "LED bulb" after the price reduction is still more than 10 times more expensive than the traditional quartz bulb with 10 times higher power consumption, the "LED bulb" has a lifespan of 35,000 hours, which is 17 times longer than the traditional quartz bulb. Enough to offset the cost of the increase.
Chen Changde, the company's managing director, said that the quartz bulb is one of the commonly used lamps in the market. When operating, it generates high temperatures. In addition to wasting energy, merchants use the products to illuminate chocolate and cosmetics. The price is believed to stimulate sales growth.
General Manager Huang Ande added that the "LED bulbs" were launched in just a few months, with global sales reaching 100,000, and Hong Kong accounted for half of the results.
The company believes that there is still no standard for testing LEDs in the world, affecting the popularity of LEDs. It is believed that the Hong Kong government can take the lead role in promoting the certification industry, setting specifications for LEDs and adding energy labels to LEDs to increase consumer purchases. confidence.
Power cables are used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, internal power supply of enterprises, outgoing lines of power stations, internal power supply of industrial and mining enterprises, and underwater power transmission lines across rivers and seas.
In power lines, the proportion of cables is gradually increasing. Power cable is a cable product used to transmit and distribute high-power electric energy in the trunk line of power system.
The structure of power cable is relatively simple, which can be divided into conductor, internal and external insulation layer, sheath, armor layer and protective layer. The conductor is mainly made of copper and aluminum, which is used to conduct current. The insulating layer is usually wrapped around the conductor to isolate the conductor and so on. There are various types of power cables. If they are classified according to voltage, they can be divided into low-voltage, medium voltage, high-voltage, ultra-high voltage and ultra-high voltage cables.
Advantages
1. Small land occupation. Generally, it is buried in the soil or laid indoors, in ditches and tunnels. The insulation distance between lines is small, without poles and towers. It occupies less land and basically does not occupy space on the ground.2. High reliability. It is less affected by climatic conditions and surrounding environment, with stable transmission performance and high reliability.
3.It has more favorable conditions for the development of ultra-high voltage and large capacity, such as low temperature and superconducting power cables.
4.Less maintenance work.
5 The possibility of electric shock is low.
