In building cabling, control panel and a variety of dry place electrical installation, THHN cable because of its excellent electrical performance and mechanical strength, become the North n market one of the first choice. Among them, the combination of PVC insulation and nylon outside the series structure of THHN line, is its excellent wear resistance, chemical corrosion resistance and easy laying characteristics, favored by engineers and installers.

Today, we'll take a closer look at this high-performance cable that meets U. S. standards and how it can achieve reliable quality with advanced extrusion technology.

Product core: PVC + Nylon THHN series line

1. Dual Protection, superior performance:

PVC insulation: as the inner layer, high quality PVC (polyvinyl chloride) material provides excellent electrical insulation, flexibility and heat resistance (usually rated at 90 °C) to prevent current leakage and short circuits.

Nylon outer layer: as the outermost layer, the nylon material gives the cable an incomparable additional advantage:

Extremely high mechanical strength: tensile, compressive, wear-resistant, in the complex process of pipe routing, can effectively protect the internal insulation from damage.

Smooth surface: low coefficient of friction, making the cable in the conduit threading more labor-saving and fast, greatly improving the installation efficiency.

Chemical Resistance: able to resist oil, mold and a variety of chemical erosion, extending the service life of cables in harsh environments.

2. Accurate packaging for easy export:

Our products are closely benchmarked against the U. S. market, offering two mainstream packaging specifications:

Over 70m/lap and 150m/lap.

These cables are wound neatly and compactly on standard spools by an efficient small-section coiling machine. This packaging method not only ensures the safety of the cable in the transportation process, avoids winding and knotting, but also provides great convenience for the end user's access and storage.

Behind superior quality: precision extrusion technology

The excellent performance of a cable, not only depends on the material, but also depends on the production process of its perfect combination. We use PVC + Nylon series extrusion technology, is to ensure that this is the key to the quality of THHN line.

In this core production line, we trust and use Jiangsu Handing Cable Machinery Co., Ltd. High performance extrusion machine. The extrusion equipment with its excellent stability, precise temperature control system and efficient extrusion capacity, the perfect realization of the two-layer material co-extrusion.

Precision co-extrusion, perfect coating: extrusion machine will melt PVC and nylon materials, through the precision die extrusion at the same time, so that the outer layer of nylon evenly, closely coated in PVC insulation. This one-piece process eliminates the gap between layers and ensures the integrity and consistency of the cable structure.

Stable and efficient, quality as one: Jiangsu Handing extrusion machine configuration to ensure that from the start to the end of production, the whole process of stable parameters. Both the uniformity of the wire diameter and the thickness control of the two-layer material meet the high standard requirements, thus ensuring that each meter of THHN wire has stable and reliable electrical and mechanical performance.
