Quality starts with customer

First of all, we try to make our customers understand the importance of making right demands from start and to provide us with complete information and requirements of their products.

Quality oriented sub-suppliers

Copper stranding

A key to good electric cables is to control the copper material. Therefore, we always do the copper stranding in-house in our own factories.

Drawings and samples

We never start mass production of any product before drawings and/or samples have been approved by customer.

Internal quality control

Our QC staff conduct regular quality inspections during production to confirm the quality and to make a final assurance that no products with quality problems leave our factories. Unless we get other requirements from our customers, our quality checks are in accordance with level II of ISO 2859, AQL major 1.0 and minor 2.5.

Test lab

In our test laboratory, we conduct regular tests of our products to ensure that they comply with all requirements from customers and that they are in compliance with national test standards.
