He leads the team

It is the first time to complete the research and development of carbon fiber composite core conductor in China

He and his team

Mainly engaged in research and development of new technologies for power equipment

And operation and maintenance technology research

He is

2020 year “ The 24th Beijing outstanding young engineer pacesetter ” winner

North China Electric Power Research Institute Co., Ltd

Professor-level senior engineer

Luyi

With the rapid development of economy

The power load increases exponentially

The transmission capacity of the original transmission line

It can no longer meet the high-speed growth of load

So the conveying capacity is large

And more energy-saving and environmental protection

Carbon fiber composite core wire came into being

at present

Our country is already

Carbon fiber composite core wire technology

Leading the world

But in order to develop this kind of wire with better performance

Chinese people have made great efforts

Traditional conductors use steel cores

If the conveying capacity needs to be improved

You need to choose a thicker wire

Then the entire transmission system such as the iron tower needs to be replaced

The cost is very high

And carbon fiber materials

It has light weight

Relatively strong

And corrosion resistance and other advantages

Wire with carbon fiber composite as core

It can give full play to the advantages of carbon fiber materials

Increase the transmission capacity for the line

Improve the safe operation level

Bring great benefits

But developed countries monopolize high-performance carbon fiber

And carbon fiber conductor technology

And the bottleneck of imperfect supporting technology

Seriously hindered

Promotion and application of carbon fiber conductor in China

Lu Yi and his team
After repeated

formula 、 Experiment and screening

Finally, a kind of

Modified bismaleic resin system

They also creatively designed

A structure resistant to longitudinal cracking

The arrangement of carbon fiber is optimized

Bypassing foreign patents

meanwhile

They studied the performance of carbon fiber composite core

It's also improved

Especially the cracking resistance

It only took a year

Luyi led the team to complete

Research and development of carbon fiber composite core conductor

After achievement appraisal

Its core indicators have reached the international leading level

The carbon fiber composite core wire has been successfully developed

It represents China's successful breakthrough in foreign technical barriers

To improve the efficiency of domestic power transmission

Reduce transportation costs

Provides more possibilities

Now

Lu Yi also led the team

Aim at emerging fields

Continue to climb the peak of scientific research

Strive to reach the peak for carbon 、 Contribute to carbon neutrality goals
