Far East Cable: Technological innovation to help the development of the photovoltaic industry on the water

As an important part of new energy, photovoltaic power generation has been "out of the circle" in recent years and has attracted much attention
.
Public data show that from 2015 to 2020, the cumulative installed capacity of photovoltaic power generation in China increased from 43.
18 million kilowatts to 253 million kilowatts, an increase of nearly 6 times, ranking first in the world; The cumulative power generation of photovoltaics exceeds 130 billion kWh, reducing carbon dioxide emissions by about 100 million tons
.
Accelerating the construction and grid connection of photovoltaic power generation projects is not only conducive to alleviating the tight situation of power supply and demand in China, but also helping to complete the goal of dual control of energy consumption and promote low-carbon energy transformation
.

The rapid development of the photovoltaic power generation industry has also injected new vitality into the upstream and downstream industrial chain, including the photovoltaic cable industry

(hereinafter referred to as Far East Stock Code: 600869) Far East Cable Co.
, Ltd.
(hereinafter referred to as Far East Cable), a wholly-owned subsidiary of Far East Cable Co.
, Ltd.
(hereinafter referred to as Far East Cable), with strong R & D and innovation capabilities, advanced equipment and all-round quality management advantages, continues to deepen its cultivation in the field of photovoltaic power generation, provides professional solutions and perfect product research and development system, and leads the development of the industry with timely and ultimate products and services
.

Photovoltaic power plants are mainly land-based, and there are also floating photovoltaic power plants
.
Floating photovoltaic power station refers to the photovoltaic power station
established on the water surface of ponds, small and medium-sized natural lakes, reservoirs, reservoirs, and lakes formed by coal mining collapse areas.
Different from traditional ground photovoltaic power plants, water photovoltaic power plants have the advantages
of not occupying land resources, high power generation efficiency, convenient module cleaning, high power station management flexibility, high cost-effectiveness, and protection of water resources.
At this stage, China has become the country with the highest installed capacity of water photovoltaic in the world, and it is also the main construction country
of large-scale water photovoltaic power plants in the world.

Floating photovoltaic power plants have higher
requirements for photovoltaic cables.
The photovoltaic cable itself needs to be often exposed to sunlight, long-term high temperature and ultraviolet radiation, outdoor laying environment is harsh, so it must have product characteristics such as anti-ultraviolet rays, ozone, severe temperature changes and chemical erosion, so as to ensure the stable operation
of the photovoltaic power generation system.
But now a new requirement has been added, that is, it must have excellent waterproof performance, if this is not done, it is easy to produce safety hazards
.

As an industry leader, Far East Cable designs corresponding system cable selection schemes for different types of power transmission systems, and develops photovoltaic power cable products
for different applications according to the cables and standards and requirements of various scenarios.
In order to meet the environmental and laying requirements of photovoltaic power plants on the water, Far East Cable has independently developed waterproof photovoltaic wires, power cables for photovoltaic and shoals on water, power cables for shallow lakes and special waterproof special lines, which greatly improves the service life of
photovoltaic power generation systems.

Among them, waterproof photovoltaic wire refers to the single-core flexible cable (wire) used on the DC side of the photovoltaic system, suitable for a maximum allowable DC voltage of 1.
8kV (core-to-core, non-grounded system), suitable for use under Class II safety level, the ambient temperature of cable operation is up to 90 °C, and the cable can be used in parallel
.
The product not only has the characteristics of halogen-free flame retardant, wind and rain resistance, ultraviolet resistance and ozone erosion resistance, but also has excellent water resistance, which can meet the special use environment of floating photovoltaic projects, and can meet the use requirements
of 25 years after life evaluation.

Power cables for floating photovoltaic and shoals are used for floating water photovoltaic project power station confluence boost and grid-connected connection, with strong environmental applicability, and can be tied and laid on the water surface with the support of the floating phalanx square array, and the laying method of multiple complex environments of direct burial after landing can also be directly sunk in shallow water environments such as lakes and riverbeds, coastal tidal flats, swamp wetlands and other shallow water environments
with a water depth of no more than 10 meters 。 The product has good waterproof, light aging and corrosion resistance, and can meet the water tension and direct burial pressure resistance during floating, and is equipped with a special waterproof traction head, making the laying safer and more convenient, and more importantly, the procurement cost is lower
.

Up to now, the photovoltaic cable products developed by Far East Cable have been used in batches in hundreds of photovoltaic power plants, including a number of water photovoltaic projects, such as Shandong Huancheng 50MW floating photovoltaic power station project, Tongcheng Shuanggang Town 100MW fishery-solar complementary photovoltaic power generation project and Xiangyin County Xiangbin Yutang Lake 4*20MWp fishery-solar complementary photovoltaic poverty alleviation power station project, etc.
, so far the performance indicators are stable, won the full affirmation
of customers.

It is true that compared with other countries, China's water photovoltaic power station industry started late, but it has the advantages of mature commercial model, rich project experience, obvious price advantage, and vast ocean area, with the continuous favorable national policy, the future development potential of China's floating photovoltaic market is huge
.
Far East Cable will continue to participate in the construction of the project, provide Far East solutions and contribute Far East wisdom
to promote the development of water photovoltaic and even the entire photovoltaic power generation industry, and build a clean and efficient modern energy system.
