A ductile power Manhole Cover is a type of manhole cover that is made from ductile iron, which is a type of cast iron that has been treated with magnesium to enhance its strength and ductility.
Overall, ductile power manhole covers offer a reliable and efficient solution for securing underground utility infrastructure while ensuring safety and ease of access for maintenance and inspection purposes.

In the recent situation of “dumping power†in some areas during the “electricity shortage†period, some people from the State Electricity Regulatory Commission told the Economic Information Daily that the multilateral power transaction being implemented in Inner Mongolia can also be implemented in other power surplus areas. . The reporter learned that, unlike the “centralized bidding†implemented in the previous regional power market, the Inner Mongolia power multilateral trading market introduced two-way competition on the “power generation side and user sideâ€, allowing large-user enterprises and power generation enterprises in the region to directly purchase and sell. The industry believes that this more flexible pricing mechanism is more conducive to reflecting market supply and demand, and truly reflects the cost of energy resources.
The reporter learned in an interview in Inner Mongolia that the multilateral trading market is based on the premise of not changing the electricity price structure of the current electricity classification catalogue, and not changing the current purchase and sale price difference of the power grid company. The large users and power generation enterprises are based on the benchmark electricity price of Inner Mongolia Power Grid. Declare the spread between the up and down, and temporarily limit the market price fluctuation by ±20%. "Through the spread of the spread, the linkage between the sales price and the on-grid price can be realized; through the linkage between the on-grid price of the power generation enterprise and the price of the user's main product, the interest interaction between the large user and the power generation enterprise can be realized; the price signal can be transmitted through the supply and demand of electricity to guide the power consumption and Investment in power construction.†Cheng Xianming, former director of the Inner Mongolia Power Multilateral Trading Center, introduced the reporter to the Economic Information Daily.
It is understood that in 2002 the State Council issued the "Power System Reform Plan" (Guo Fa [2002] No. 5), clearly proposing to establish a competitive, open regional electricity market and implement a new electricity price mechanism. A person who did not want to be named by the State Electricity Regulatory Commission said in an interview with the Economic Information Daily that according to the original national power reform plan, the regional power market was basically established by the end of the "10th Five-Year Plan" period. However, to this day, the construction of the regional power market is progressing slowly, and the transaction distance from the real market is very large. “The pilots of direct power supply for power generation enterprises and large users in the region have not been effectively rolled out, and they have not been able to change the pattern of exclusive purchase of electricity by power grid enterprises. â€
Since 2004, the Northeast Power Market, the East China Power Market, and the Southern Power Market have started pilots one after another, but the transaction power is very low, and soon they have not ended. “In 2004, the first regional electricity market was piloted in the northeast. At that time, the relevant departments planned to carry out pilot projects for bilateral transactions between power generation companies and large users in a step-by-step manner. However, the northeast regional power market has very little transaction volume, and the competitive power accounts for the actual transaction volume of the regional power market. To 20%, it can be seen that the relevant departments are cautious about the implementation of the regional power market." A person from the SERC who participated in the construction of the Northeast power market told the Economic Information Daily.
In addition, local interests are also a problem in the face of regional power market reforms. According to the above-mentioned person, even in different provinces and cities in the northeast region, there are differences of position. "Heilongjiang, a major power generation province, is very enthusiastic about establishing a regional power market. Liaoning Province is more cautious about the regional power market." The reporter learned that East China Power At the time of market trials, Anhui, Fujian and other places have different interests with Jiangsu, Zhejiang and Shanghai.
An important factor in choosing to push the regional power market in the Northeast is that the power in the Northeast is relatively surplus in the context of tight national power balance. "This ensures that at the beginning of the pilot of the bilateral trading in the northeast power market, centralized bidding will allow the on-grid tariff to fall, which will also protect the interests of grid companies. But then the price of coal rose, leading to an increase in the online bidding of the northeast power plant. The 'reservoir' that cushioned the price fluctuations and brought profit to the grid companies did not play its previous role," said the SERC.
Due to the above reasons, there has been such a phenomenon in the pilot of the northeast power market. In the northeast power grid area, the northern power generation has a high price for Internet access, and the southern electricity market is sold at a low price, so that the Northeast Power Grid Company lost RMB 3.2 billion in 16 days.
Ductile power manhole covers are designed to withstand heavy loads and provide a durable and long-lasting solution for covering underground utility access points. They have a high load-bearing capacity, making them suitable for areas with heavy traffic, such as roads, highways, and industrial sites.
These manhole covers are typically round or square in shape and feature a solid design with reinforced edges to prevent cracking and breakage. They are often equipped with lifting handles or lifting points for easy access and removal during maintenance or inspection activities.
Ductile power manhole covers are known for their resistance to corrosion, making them suitable for use in various environments, including urban, coastal, and industrial areas. They are also designed to be slip-resistant, providing a safe walking surface for pedestrians and vehicles.
Additionally, these manhole covers may have features such as locking mechanisms or anti-theft devices to prevent unauthorized access or theft. They can also be customized with logos, markings, or color-coding to indicate the type of utility or service they cover.
Regional power reform is brewing and breaking the issue, the Electricity Regulatory Commission will promote multilateral trading in the electricity market.
The pilot of power multilateral trading in Inner Mongolia may bring a breakthrough to the reform of the domestic electricity price system. As a result, the slow progress of regional power market reforms in the past nine years may be changed.
