Frequently Asked Questions

What is driving the growth of the bimetallic conductor market?

Key drivers include: electrification trend (EVs, data centers), lightweight demand (automotive, aerospace), cost pressure from high copper prices, and sustainable development requirements (resource efficiency, carbon reduction).

Which application segments offer the best growth potential?

Power cables (35-40% share), communication cables (20-25%), and automotive wire harnesses (15-20%) are the largest segments. New energy vehicles show the fastest growth potential with CCA substitution rates of 50-70% in low-voltage harnesses.

What are the barriers to market growth?

Barriers include: limited customer awareness of CCA performance, missing standards in some applications, certification recognition needs improvement, and concerns about connection reliability in certain applications.
