Quality Control
We produce high-quality products day after day because we always put quality control first. We have established a comprehensive quality control system to ensure that the performance of our products is close to perfection.
To make sure all department get in line, technical department have all details toquality management on file, all we have to do is follow the instruction, generate test report on department, system work bonding together will ensure quality control stay well in operation.
We believe cable knowledge always be the key to help our employee succeed in everyday role, technical department gives training course on plan, help everyone have better understanding of materials and compliance requirements
Test department have the whole device to generate precise lab result. Only good would be received in warehouse, otherwise we deal with it like contract policy called.
Every process guarded by someone all the time, usually powered by head of technical department, test department give assistant help, make sure everything under control.
Our test department have 5 lab rooms to run the whole test, all raw material, semi-finished products, fully done pieces would go over sampling inspection, and file it. Standard will see client needs, only qualified pieces shot out.
All lab device maintenance go over every two weeks, test department take the responsibility to make sure data on report always right.
Since lab test gives bad news, all defective product will be spotted, technical department have meeting and verified the problem till there is nothing wrong with it, then they approve it.
All files secured in document room, refer to handling, storage, packaging, protection, and delivery, etc. Any parts gives quality problem, we have tracking system to spot where and how it comes.
Copper Wire Rod: Oxygen-free copper rod, given by round clean smooth surface, no any burrs,crack, visible mechanical damage and oxidation discoloration. Diameter error and Volume resistivity at 20 ℃ can be acceptable.
Aluminum Rod: L4/L9 Aluminum rod, given by round clean smooth surface, no any burrs,crack, greasy dirt and visible mechanical damage. Diameter error and Volume resistivity at 20 ℃ can be acceptable.
XLPE Granule and PVC(normal or flame-retardant) For Sheath and Insulation:Clear visual gives even color granule with no impurities. Tensile strength, elongation at break, and volume resistivity all meet standards.
Armored Tape:Steel tape/steel wire, Thickness and wideness error must be reasonable, gives clean smooth non-defective surface.
Jacket:Gives even black color granule, no powder left, shape like one piece. Tensile strength and elongation at break must be acceptable.
