Exhibit Details
Complete range of 10 kV–35 kV European- and American-style cable accessories

Complete range of 10 kV–35 kV European- and American-style cable accessories

The European‑ and American‑style cable accessory series comprises fully shielded, separable cable terminations designed for power cables. These terminations are manufactured via integral injection molding using EPDM rubber, offering complete insulation, hermetic sealing, and touch‑safe operation. They are primarily used for cable connections in European‑style ring main units, cable distribution boxes, packaged substations, and similar equipment, providing safe and reliable electrical connections and protection for 10 kV to 35 kV distribution networks. Constructed from high‑quality EPDM rubber through integral injection molding, they deliver outstanding insulation performance, with power‑frequency and impulse withstand voltages that meet industry standards, thereby ensuring the safety of electrical connections.

Complete range of 10 kV–35 kV medium- and high-voltage insulators and instrument transformers

Complete range of 10 kV–35 kV medium- and high-voltage insulators and instrument transformers

A complete range of insulating components for 10 kV–35 kV gas-insulated switchgear and eco‑friendly switchgear, including bushings. These are high‑voltage epoxy‑cast insulation parts, manufactured from APG epoxy resin that is free of bubbles and cracks. Gas‑insulated switchgear bushings must simultaneously meet stringent requirements for both electrical insulation and gas tightness, with exceptionally precise sealing surfaces. Electrical performance: partial discharge ≤ 3 pC; withstand voltages under power frequency and lightning impulse comply with the relevant voltage class. Environmental conditions: operating temperature range from –40°C to +125°C; optional versions can be designed for high‑altitude applications with enhanced creepage distances. Typical applications include indoor switchgear, gas‑insulated switchgear, ring main units, outdoor packaged equipment, and environments characterized by high humidity, salt spray, or dust.

Full range of 1 kV–35 kV cold-shrink cable accessories

Full range of 1 kV–35 kV cold-shrink cable accessories

Cold-shrink accessories for 1 kV–35 kV cable terminations are manufactured using high‑performance silicone rubber from a publicly listed company, delivering excellent insulation performance and reliably withstanding the operating voltages of the respective systems. Their power-frequency withstand voltage and impulse withstand voltage meet industry standards. By relying on their inherent, consistent radial clamping force, these accessories provide insulation, electric field control, sealing, and protection at the cable termination—without the need for heating tools—ensuring high safety, easy installation, superior weather resistance, and strong compatibility with various conductor sizes. They are widely used in both indoor and outdoor cable termination applications, helping to ensure the safe and stable operation of cable terminations.
