- May 28, 2019-

An Electrical Industry Co., Ltd. is an electrical professional enterprise which specializes in the production and development of automobiles, motorcycles, locomotive electrical appliances and wiring harness assemblies. The main products of customers are automobile wiring harness, using our products: single-walled tube and double-walled tube.

In 2016, in order to control the quality of products, from the start of production, we strictly controlled the secondary matching manufacturers. After layer by layer screening and related testing, we selected our 3:1 environmental friendly double-wall heat shrinkable tube.

The company produces dozens of models of automobiles, locomotives harness products are mostly used in our thermal shrinkage series products.

In the two years of cooperation with the company, Xiaobian also summarized the related matters needing attention when using double-wall heat shrinkable tube in locomotive harness and the problems encountered in cooperation. Here, Xiaobian gives a list to illustrate each other, which has been for everyone to learn from each other.

1. In the use of double-walled tubes, there are cases of copper wire breaking:


A. When using, the worker should pay attention to the surface of the object covered by the lower double-wall pipe not too sharp, in order to avoid being punctured.

B. Use double-wall heat-shrinkable tube with slightly larger size instead.

2. Questions about order and long delivery time:


A. Considering the production cycle, Logistics Impact and long-distance customers, customers should be ordered in advance as far as possible, or the customized specifications of heat shrinkable tubes should be manufactured in advance to retain inventory.

B. In the event of holidays, especially during the Spring Festival, the holidays may not be synchronized between the two sides. Salesmen should contact customers in advance whether to reserve orders for inventory.
