Tianjie's attitude towards products: Material

Focus

    Every year, the State Grid will participate in bidding for cable manufacturers to carry out product quality sampling and testing. Unfortunately, every year will notify a large number of unqualified product quality inspection manufacturers, including manystate-owned enterprises, listed companies. From the sampling results, the quality of the problem is more focused on the performance of insulation materials and sheath materials failed. For example: tensile strength and elongation at break before aging; thermal extension of cross-linked polyethylene insulation; unqualified performance after aging; heat loss; flameretardant fails to meet the requirements and so on. Whether consciously or unconsciously lead to product quality problems, the prevalence of this phenomenon explains what? Most of the cable production and manufacturing enterprises quality awareness is not strong, backward manufacturing process,poor material quality is still the biggest problem of traditional cable production.

Material Standards

   As we all know, not only the cable has the corresponding standards, butalso all the materials constituting the cable have the corresponding standards,and conforming to the standards is the minimum requirement. Wire and cable havethe corresponding electrical properties, mechanical properties, weathering performance and aging performance, flame retardant properties and so on. These performance requirements are strictly speaking by the corresponding insulation materials and sheath materials to achieve and get continuous guarantee.

   Many civilian line on the market(such as BV) materials, in order to reduce the cost of the formula to add alarge number of toner, resulting in an increase in specific gravity, but at the same time greatly undermined the mechanical properties of the material, greatly reducing the tensile strength and elongation at break, the majority of people who do not understand the wire thought that the weight of the wire is heavy enough to use the amount of copper, the wire is easy to peel the skin of the materialis good, in fact, can't really be so easy to draw the same number.

Cables used in the field of securitycables need to meet certain flame retardant standards, especially some bundles of flame retardant requirements of the cable. Because of the high flame retardant requirements need to add a certain flame retardant, flame retardant will affect the mechanical properties of the cable, so the high level of flame retardant cables from the structural design, material selection and manufacturing process have a certain degree of difficulty. Can the so-called flame retardant cables on the market achieve the real flame retardant test?Only the benevolent see the wise see the wise.

The quality of the material will directly lead to the wire and cable transmission performance decline, service life reduction, etc. can not meet the use of requirements, the more serious and even cause personal and property safety.

With the continuous progress of the cable industry and materials industry, cable materials used from the original most common polyvinyl chloride(PVC) and polyethylene (PE) to more environmentally friendly and saferlow-smoke halogen-free (LSZH) materials, a variety of modified materials with higher performance (TPU, TPEE) and other changes to deal with cables in avariety of use of the environment under the harsh requirements. Of course, the mature production process is also a guarantee to give full play to the performance of cable materials.

Our Products

Tianjie's products adhere to standard materials as the basis, and insist on excellent product technology andadvanced testing technology to ensure that our products meet the requirements of the corresponding standards. The production line is equipped with advanced on-line monitoring system, and we have established our own CNAS laboratory and combustion laboratory to ensure that our products meet the needs of our customers in terms of production technology and quality control. Of course, we have also made some breakthroughs in the practical use and exploration of new modified materials, which has laid a solid foundation for the benign development of the company.

Tianjie adhere to the original intention, thirty years of consistency, to do business and do people the same, only quality to win customers, in order to get the respect of the market!
