Insulation: Polyethylene (PE) - a loyal defender of signal integrity

Insulation plays a key role in cable systems to ensure safe and stable operation, and its core mission is to eliminate current leak age and short-circuit hazards to build asolid defence for the integrity of signal transmission. Polyethylene (PE), with its excellent electrical insulation properties, excellent chemical resistanceand low dielectric constant, is widely used in the insulation of security communication cables, and has become a good choice for guarding signal transmission.

For TIANJIE, these lection and application of PE insulation materials fully demonstrates its profound professional background and exquisite technical level. The company carefully selects PE materials provided by internationally renowned suppliers,which have reached extremely excellent levels in key indexes such as dielectric constant and dielectric loss angle tangent, laying a solid foundation for the excellent performance of the cables. Each batch of PE materials must under gorigorous physical, mechanical and electrical performance tests and thermalaging tests to ensure that they can still maintain stable and reliable performance for a long period of time under high temperature, high humidity and other harsh environments.

In production practice, TIANJIE uses advanced three-layer co-extrusion technology to ensure that the PE material is evenly and tightly wrapped around the surface of the conductor, ensuring that the thickness of the insulation layer is precisely the same. Each step in the production process is under precise control, and the thickness of the insulation layer can be precisely controlled within ±0.02mm, thus effectively guaranteeing the high stability of insulation performance. In addition, for special application scenarios where environmental protection and safety are of utmost importance, TIANJIE has also successfully developed Low Smoke and Halogen Free Polyethylene (LSZH-PE). This innovative material does not releasetoxic and harmful gases when burned, which fully reflects TIANJIE's deepconcern for users' lives and safety as well as its high sense of responsibility for the cause of environmental protection.

TIANJIE's strict requirements for PE insulation materials are not only reflected in the carefulselection of raw materials, but also in the entire production process. Frommaterial extrusion to cooling and moulding, each process is equipped with astrict quality inspection barrier to ensure that the insulation performance is always maintained in the optimal state through layers of control. It is this extreme pursuit of quality and unremitting efforts that make Tianjie Cable winwide acclaim and high recognition in the market, and become a model of excellent quality in the industry.
