The company is also ranked first with the installation of 12,000 user smart meters and meters in the service area. The company successfully completed the smart grid project utility company.

Smart grid losers -

1.Beacon Power

Beacon Power, headquartered in Massachusetts, is a supplier of flywheel energy storage systems. It received US federal stimulus funds and state loan guarantees but filed for bankruptcy this year.

2. Solyndra and the U.S. Department of Energy loan guarantee program are also the recipients of the stimulus fund. Solyndra, a supplier of photovoltaic modules in California, eventually declared bankruptcy after receiving a USD 535 million loan guarantee from the US Department of Energy. This loan guarantee program It is currently under consideration.

3. Pacific Coal Power Co., Ltd. Speaking in a fair word, Pacific Coal and Power Company deployed millions of meters, which is a major achievement. In addition, it also depicts a comprehensive and creative smart grid roadmap. However, the company does not seem to know how to please the media and the public and continues to suffer from all kinds of negative news.

4. Xcel Energy Xcel Energy Completes the Smart Grid Project in the People's Republic of China, Recognized as the Most Complete Smart Grid Project in the United States, but due to cost overdrafts, regulatory wrangling, and controversy over the proportion of coal-fired power generation The citizens of Boulder voted to resolve the partnership with Xcel Energy and set up a municipal power company.

5. Illinois State Governor Pat Quinn at the Illinois General Assembly, politicians, unions, and smart grid supporters after a fierce debate, eventually voted to overthrow Governor Pat Quinn's rejection of smart grid legislation, for the federal Edison Corporation Continuing to build a smart grid creates the conditions.

6. Congress We don't want to intervene in politics, but Congress is currently deadlocked and we can't ignore it because it has hindered the progress of energy policy and made some valuable programs such as ARPA-E awake.

7. Northeast utility companies spend millions of dollars on energy storage, but after a rare snowstorm in the northeastern United States in October, governors, senators, and others have begun to appeal to utility companies. Emergency preparedness and response capabilities were investigated.

Smart Grid Wall Ride -

1. The overruling of the ComEd Governor’s veto did indeed ensure that the smart grid can continue, but in the face of major performance indicators, can the company honor its smart grid commitments?

2. Federal Energy Regulatory Commission This committee has made some necessary amendments to the transmission planning and cost allocation rules, but can they persist in this reform and will it be overridden by opponents?

3. Broadband Power Lines Although broadband powerline technology is not favored in the United States, it has broad prospects in India. The UK, which has a different network architecture, has also proved to be a more manageable technology.

4. From the positive perspective, Yinquan Networks has continuously grown and expanded: to build an industry-leading platform, submit initial public offering applications, and announce new financing plans. However, from a negative perspective, we do not know whether it will succeed in public offerings in the near future. If not, the company will suffer major failures this year.

5. Zigbee company once had a period of time, Zigbee company seems to have become the benchmark of the home area network, but increasingly fierce competition to curb this momentum.

6. The tax incentives for the renewable energy industry that have a huge boost for the renewable energy industry are expected to end. This may mean that no new incentive mechanism will be introduced. In response to this political and economic reality, many companies have pinched sweat.

7. The Obama Administration In October, the Obama administration announced the launch of a pilot project for the modernization of power grids. The purpose of the project is to enable the plans for the proposed seven transmission lines to pass the deliberation as soon as possible and eventually build a transmission network that runs through the United States. Can it succeed? (Guo Guoying, Guotong Telecom, Fan Yingying)

Power cables are cables used to transmit and distribute electrical energy. Power cables are commonly used in urban underground power grids, power station outlet lines, internal power supply for industrial and mining enterprises, and power lines under river water.

In power lines, the proportion of cables is gradually increasing. Power cables are cable products used to transmit and distribute high-power electrical energy in the backbone of power systems, including various voltage levels from 1-500KV and above, and various insulated power cables.

The use of power cables has been around for more than a hundred years. In 1879, the American inventor T.A. Edison wrapped jute around a copper rod and put it into the iron pipe, and then filled the asphalt mixture to make a cable. He laid the cable in New York and created underground power transmission. The following year, the British Karende invented the asphalt impregnated paper insulated Power Cable. In 1889, the British S.Z. Ferranti laid a 10 kV oil-impregnated paper insulated cable between London and Dartford. In 1908, the UK built a 20 kV cable network. Power cables are becoming more widely used. In 1911, Germany laid a 60 kV high-voltage cable and began the development of high-voltage cables. In 1913, the German M. Hoichstedt developed a phase Shielded Cable, which improved the electric field distribution inside the cable and eliminated the tangential stress of the insulating surface, which became a milestone in the development of power cables. In 1952, Sweden laid a 380 kV ultra-High Voltage Cable in the northern power plant to realize the application of ultra-high voltage cable. By the 1980s, 1100 kV and 1200 kV UHV power cables were made.
basic structure

The basic structure of the power cable consists of a core (conductor), an insulating layer, a shielding layer and a protective layer.

Folding core

The core is the conductive part of the power cable that is used to carry electrical energy and is the main part of the power cable.

Folding insulation

The insulating layer electrically isolates the core from the earth and the cores of different phases to ensure electrical energy transmission, and is an indispensable component of the power cable structure.

Folding shield

Power cables of 15KV and above generally have a conductor shield and an insulating shield.

Folding protective layer

The role of the protective layer is to protect the power cable from external impurities and moisture, and to prevent external forces from directly damaging the power cable.
