Design and laying of submarine cable

The design of submarine optical cable: anti-corrosion, anti-seepage, but also against sharks, compared with coaxial cable, optical fiber is quite obvious advantages, but its own is quite fragile, so this protection of optical fiber submarine cable peripheral protection structure put forward higher requirements. Specifically, the design of submarine optical cable must ensure that the internal … Read more

What is aluminium alloy power cable?

Aluminum alloy power cable is a new material power cable with AA8030 series aluminum alloy material as the conductor, adopting advanced technology such as special roll forming wire twisted production process and annealing treatment. Alloy power cable made up for the inadequacy of previous pure aluminium cable, although there is no improve the conductive properties … Read more

This summer, U.S. electricity demand fell to its lowest level since 2009

Summer electricity demand in the US is expected to be the lowest since 2009, according to the US Energy Information Administration. The summer demand level from June to August is expected to be 998 billion kilowatt-hours, down 5% from last summer’s demand, the report said. The lower power demand is mainly due to the coronavirus … Read more

Photovoltaic cable under the epidemic

A sudden outbreak in the beginning of the year disrupted the development and construction rhythm of downstream photovoltaic power cable stations, and a large number of projects may be difficult to be connected to the grid as scheduled.Photovoltaic cable under the epidemic.

According to the policy, the bidding photovoltaic project in 2019 should be completed and connected to the grid by the end of the year. If it is not connected to the grid, the price subsidy will be reduced by 0.01 yuan/kWh for each quarter of the overdue; if the grid is not completed and connected to the grid within two quarters of the overdue , Disqualification of project subsidies.

 

According to industry estimates, the scale of unsuccessful carry-over bidding projects in 2019 is about 12GW. From January to March, the country’s new photovoltaic installations will be 3.95GW, most of which are carried-over projects in 2019. Based on this estimate, there are still 8GW The project is faced with “630” pre-installation.Photovoltaic cable under the epidemic.

Nan Cunhui, member of the Standing Committee of the Chinese People’s Political Consultative Conference, vice chairman of the All-China Federation of Industry and Commerce, and chairman of Chint Group, said in the “Proposal to Extend the Term of Grid-connected Photovoltaic Power Stations in 2019” that the construction of domestic photovoltaic power plants in the first quarter was basically at a standstill, and construction started in late March The rate is only about 35%, about 65% in mid-April, and a large number of projects are difficult to connect to the grid as scheduled. However, for other regions outside Hubei affected by the epidemic, no policy has been issued for the extension of the bidding project grid connection, which will have a greater impact on the domestic photovoltaic market and enterprise operations.Photovoltaic cable under the epidemic.

Nan Cunhui said that without the support of subsidies, about 6GW of projects across the country are expected to choose to abandon construction, and about 24 billion yuan of investment will be lost. A large number of photovoltaic companies are facing the risk of inventory backlogs and profit declines and are even forced to stop production.Photovoltaic cable under the epidemic.

Not only the “630” project, at the industry public meeting, according to Hu Yidong, member of the Party Committee and deputy general manager of the Yellow River Upper Hydropower Development Responsible Company (hereinafter referred to as the Yellow River Hydropower) of the State Power Investment Corporation, affected by the epidemic, the “930” developed by the Yellow River Company “The project is also facing pressure on grid connection. In the 5GW new energy configuration project of the Qinghai Hainan UHV transmission base, the Yellow River Hydropower won the 4.1GW wind and solar project, of which the photovoltaic project scale was 2.4GW (including the size of the consortium). According to the construction progress requirements, the project should be completed and connected to the grid by September 30, 2020. If the full capacity is not completed and scheduled to be connected to the grid, the grid-connected electricity price will be reduced by 0.01 yuan/kWh every month beyond the deadline. By December 31, 2020 If the full capacity cannot be built and connected to the network, the project subsidy qualification will be cancelled.

Hu Yidong said that due to the sudden outbreak, the 4.1GW wind and light project “930” grid connection is under great pressure. From the current judgment, the entire project’s full-capacity grid connection may be delayed until the end of November. The photovoltaic project may reach 80% by September 30. ~90% capacity is put into production.Photovoltaic cable under the epidemic.
