The ten most in-demand wire and cable in China

China's wire and cable production and sales are the world's first, but there are many
problems.
For example, the well-known low industrial concentration, serious convergence of enterprises in product varieties and technology selection, lack of core competitiveness, forming a trend
of homogeneous competition in the industry.
In addition, there are very big deficiencies
in terms of technology compared with the international community.
The most prominent problem is that local wire and cable companies have not kept up with the pace of wire and cable research and development in the world today, although they have also made certain achievements in local technology, but they are still weak in high-end wire and cable research and development, and it is difficult to compete with international cable giants and so on
.
These are the bottlenecks
restricting the development of China's wire and cable industry.

However, in the wire and cable market with serious overcapacity, there are still many products that are urgently needed by the
market.
Like what:

(1) Optical fiber composite overhead ground line (OPGW) Optical fiber composite overhead ground line has a variety of functions such as communication, remote telemetry and data transmission, which is suitable for the management automation of 110~500kV high-voltage and ultra-high-voltage overhead transmission lines, with high
reliability.

(2) Nuclear power plant cables Nuclear power plant cables are distributed in the nuclear island, conventional island and BOP parts of the nuclear station, used for power transmission, control, computers, instruments, etc.
, and the types of cables required for a nuclear station are basically the same
as those of thermal power stations.
However, due to the very strict requirements for technical performance such as halogen-free, low-smoke, and low-toxicity cables in nuclear power plant cables, China can only produce wires and cables for the periphery of nuclear islands, and most of the rest can only rely on imports
.
There are 276 nuclear power plants in the world, generating 343,792 MWh, accounting for 17% of the world's total power generation, and more than 10 countries account for 25%
of their total power generation.
It is expected that by 2010, China's installed nuclear power capacity will reach 20,000MW, accounting for 17% of China's total power generation, with great development potential
.
Therefore, cables for nuclear power plants have good market development prospects
.

(3) Low-smoke low-halogen, low-smoke halogen-free flame retardant cable The product is mainly used in some important places such as subways, tunnels, oil platforms, ships, power stations, etc.
, and the above related industries are currently in a stage of rapid development, which will further stimulate the demand
for this product.

(4) Wiring for automobiles China's automotive industry will maintain sustained and rapid development
.
In 2000, the annual production of cars and trucks is expected to reach 3 million units, so the demand for this product is very large
.
The future development trend of this product is high temperature resistance, high damping, thin-walled type and shielded type
.

(5) High flame retardant cable At present, the domestic mass production of flame retardant cables are mostly C grade, B grade, A class is still in development, which is still a big gap with the requirements of many high-quality engineering projects in China, the development direction in the future period is to reach A grade flame retardant complete supporting various cables
.

(6) Broadband and local network cables for intelligent buildings (Category 5, Category 6 cables) The product also has a variety of signal functions such as transmission telephone, fax, video phone, and anti-theft alarm, also known as electronic cable
.
This product already accounts for more than
20% of all insulated cables in the United States.
With the rapid development of intelligent buildings, computer industrialization and information highway projects in China, the demand for this cable will also be increasing
.
At present, the transmission rate of the cable has reached 100Mb/s (that is, Category 5 cable), and will reach 320Mb/s
in the future.

(7) High-performance winding wire B-grade polyester enameled wire still accounts for 90% of domestic enameled wire, while in Japan its proportion has dropped to less than 30%, while domestic products in terms of size control, performance indicators, etc.
, are far from
similar foreign products.
In the future, the focus of technology development should be on high-performance, multi-layer composite structures and fine enameled wires
.

(8) ribbon optical cable foreign key development of thin-layer large core number of user ribbon optical cable, 1000 core technology has matured, is currently developing 2000 cores to 4000 cores, China is still in its infancy, only 108 cores have been developed, need to be vigorously developed, to meet the development needs
of information highway engineering.

(9) 110kV and above high-voltage cross-linked cable accessories Cable accessories are important supporting products of cables, it will directly affect the operation quality of transmission lines, domestic has introduced more than 110kV cross-linked cable production lines 27, and will be put into production one after another, its total production capacity can fully meet the market needs
.
However, 110kV and above high-voltage cross-linked cable accessories are currently produced in small quantities by only 3 domestic enterprises, and their output and voltage levels are far from meeting the development needs
of the power industry.

(10) Submersible pump cable High temperature resistant submersible pump cable is a supporting product of oil production pump, with the vigorous development of Northwest Oilfield and the deepening of the diving work of old oilfield, the high temperature resistance of submersible pump cable is higher
.
Domestic production capacity has developed rapidly, but product quality and life are not satisfactory, in the future, we should be committed to improving quality and developing higher temperature resistant submersible pump cables
.

(11) Special overhead line Although special overhead lines with special requirements can be produced in China, there is still a big gap
between them and foreign advanced levels in terms of high heat resistance, high corrosion resistance, creep resistance, flexibility, high conductivity and other technical properties.
Another example is split overhead lines, which have gaps in technical performance indicators such as corrosion resistance, vibration prevention, ice and snow prevention, low corona loss, low arc halo loss, low arc volume, and double capacity
.
In order to meet the needs of special wires and cables for major projects such as the Three Gorges, special overhead lines need to be vigorously developed and improved
in product varieties and product performance.
