At present, the intelligent power grid project is flourishing, and the construction of distributed power stations is also vigorously promoted, which puts forward higher requirements for the electrical safety performance of high-voltage cable joints. The original conventional coating materials can no longer meet the higher performance requirements of flame retardancy and voltage breakdown resistance.

At present, in the selection of inserts, most of them use: 1. brass; 2. Zinc aluminum alloy; 3. Stainless steel (anti-corrosion, corrosion-resistant);Defect Solution | Rolling Plastic Fuel Tank Science Popularization -2- Principle and Solution of Coating Problem ② Temperature and Embedded Parts (Expert Article) At present, in the selection of inserts, most of them use: 1. brass; 2. Zinc aluminum alloy; 3. Stainless steel (anti-corrosion, corrosion-resistant); The basic components of embedded assembly are: 1. Embedded screws; 2. Mold cavity wall; 3. Embedded components; Material selection for inserts: 1. Good thermal conductivity; 2. Sufficient mechanical strength (details will be elaborated in the next section).

Rotomolding HDPE, short for rotationally molded high-density polyethylene, is a specialized thermoplastic material used in the production of large, seamless, and durable hollow products. The rotomolding process involves heating powdered HDPE resin inside a rotating mold, ensuring even material distribution and the formation of stress-free structures. This technique has gained immense popularity across industries such as automotive, agriculture, marine, and chemical storage due to its ability to produce complex shapes with exceptional strength and longevity.

​TS505U20CP is an external lining material designed specifically for harsh environments. It combines a variety of superior properties to effectively cope with complex outdoor and corrosive conditions.

Among rotomolding materials, Nylon 12 (PA12) stands out with its unique performance combination. As a key member of the long-carbon-chain nylon family, Nylon 12 features longer molecular chains and lower amide bond density, resulting in an extremely low water absorption rate of approximately 0.25% — the lowest among all nylon products. Additionally, it boasts low density, excellent low-temperature toughness, and outstanding oil and chemical resistance. It maintains good toughness even in extreme cold environments as low as -70°C, with a long-term service temperature reaching 80-90°C.
