Scope of application
The raw materials of winding wires for electrical equipment or the deep processing raw materials in the field of corresponding wires and cables have extremely excellent electrical conductivity and machining performance.
Service conditions
Extremely excellent processing characteristics determine the low requirements of materials for use.
Delivery requirements
l Packed in circles and bundled well;
l The package is damp proof. Anti pollution and anti mechanical damage measures;
l Allow both parties to agree on the packaging
Scope of application
It is used in the field of wires, cables and electrical equipment products. Its excellent conductivity and formability make it widely used, mostly for outgoing lines and connecting lines, or as raw materials for further processing.
