Key Application Scenarios
Substation Integration
Designed for 10kV-45kV GIS substations, AIS substations, switchgears, and distribution rooms. Our accessories address insulation breakdown, stress concentration, and leakage issues, ensuring stable operation of unmanned intelligent substations.
Urban & Rural Grid Modernization
Ideal for 0.6kV-35kV main and branch distribution networks. They replace aging accessories to eliminate faults such as tripping, overheating, and water ingress, significantly improving grid reliability and safety.
Renewable Energy Projects
Perfect for solar power plants, wind farms, and energy storage stations. Featuring excellent weather resistance, they withstand extreme temperatures, UV radiation, and sand erosion for long-term outdoor operation.
Heavy Industrial Facilities
Suitable for chemical plants, mines, and metallurgical facilities. Our products resist oil contamination, corrosion, and vibration, effectively preventing joint loosening and short circuits in harsh industrial environments.
Urban Infrastructure
Used in underground cable networks, bridges, tunnels, commercial buildings, and residential complexes. They support direct burial, conduit installation, and cable tray installation, meeting strict municipal engineering standards.
Harsh Environment Applications
Custom-engineered for coastal salt-spray areas, high-altitude regions, chemically corrosive zones, and humid conditions. Reinforced protective structures and anti-corrosion materials extend service life by 50% compared with standard products.
Core Technical Advantages
-
Superior insulation performance: High-purity polymer materials provide excellent dielectric strength and voltage withstand capability, effectively dispersing stress at cable ends and preventing insulation breakdown.
-
100% waterproof sealing: Multi-layer sealing structures with specialized sealants create a gap-free barrier against water, moisture, and dust, ensuring reliable operation in underground and tunnel environments.
-
Extreme weather resistance: They operate reliably from -40°C to 120°C. UV-stabilized and corrosion-resistant formulations prevent cracking, hardening, and degradation during long-term outdoor service.
-
Easy installation: Cold-shrinkable products require no heat source, enabling safe, fast installation in confined spaces. Heat-shrinkable and prefabricated options offer uniform contraction and precise fitting.
-
Maintenance-free operation: Scientific stress distribution design eliminates overheating and partial discharge risks. Once installed, the products deliver decades of reliable service with minimal maintenance.
-
Universal compatibility: Compatible with all major cable types, including copper, aluminum alloy, YJV, VV, and YJV22. Standardized dimensions ensure seamless integration with new and existing systems.
