Hubei Hongqi Zhong Yi standard national standard line, 2.5 is now 133. Each roll of Zhong Yi wire is marked with resistance value, insulation thickness, single-core thickness, weight and meter number. Many friends around me use red flag Zhong Yi national standard wire for home decoration. Including the Zhong Yi wire recommended by the decoration company. After all, if we dare to put quality on the line and put it on the trademark, we must have confidence.
