Electrical Silicone Tubing — Insulation, Protection & Sealing for Power Applications
Yutian is a vertically integrated manufacturer with three specialized factories spanning silicone raw materials, compounding, and precision extrusion. By owning the entire production chain — from material formulation to finished tubing — we deliver electrical-grade silicone tubing with consistent quality, batch-to-batch traceability, and full regulatory compliance. With 20+ years of silicone expertise, 5,800m² of production floor space, and 14+ extrusion lines, we have the scale and capability to support projects from rapid prototyping to high-volume production.
Our electrical silicone tubing portfolio covers the full spectrum of power and communication applications. Insulating silicone tubing provides high dielectric strength (>25kV/mm) for cable insulation and component protection. Conductive silicone tubing offers stable surface resistivity for EMI shielding and static dissipation. Cold shrink tubing (1kV, 10kV, 35kV) delivers IP68 waterproof sealing with 4:1 shrink ratio and tool-free installation — 60% faster than heat shrink. Silicone self-amalgamating tape provides emergency repair, insulation, and arc protection with self-fusing properties. All products operate reliably from -40°C to +200°C, with UV, ozone, and weather resistance for 20+ year outdoor service life.
Our cold shrink technology eliminates the need for heat guns or torches — simply pull the core and the tube contracts instantly, forming a permanent "living seal" with constant pressure that adapts to cable movement and thermal cycling. Platinum-cured silicone ensures no peroxide residues, no odor, and no volatile compounds — pure, safe, and long-lasting. We offer full customization — pre-shrink ID (20–80mm), length (50–500mm), shrink ratio (3–5x), color, hardness, built-in mastic, and voltage rating (1kV–35kV). From power cable terminations and telecom base stations to transformer bushings and rail transit — we deliver exactly what your application demands.
