Our Direct Current High Voltage Cable Accessories stand as a cornerstone in modern power transmission infrastructure, meticulously engineered to address the rigorous operational demands of HVDC (High Voltage Direct Current) systems.

|---|---|
Encompassing a comprehensive range of components such as terminations, straight joints, elbow joints, and cable connectors, these accessories are specifically designed to manage voltages exceeding ±500 kV while maintaining industry-leading power loss rates below 0.02% per kilometer. Constructed using a proprietary blend of corrosion-resistant epoxy composites and advanced XLPE-based insulation, they deliver exceptional performance in extreme environments—from sub-zero polar regions to high-humidity coastal areas. Whether deployed in offshore wind farm interconnections, transnational grid synchronizations, or large-scale industrial power distribution networks, these accessories ensure uninterrupted power flow with a mean time between failures (MTBF) exceeding 15,000 operational hours.
High Voltage Resistance: Rigorously tested to withstand ±800 kV transient voltages and continuous operation at ±660 kV, these accessories incorporate multi-layer insulation structures that prevent partial discharge even under thermal cycling conditions.
Conductive Shielding: Equipped with a 0.1mm thick electrolytic copper tape shield helically wrapped with uniform tension, effectively reducing electromagnetic interference (EMI) by up to 90% and ensuring signal integrity in adjacent communication cables.
Insulation Fluid Technology: Utilizes high-purity silicone-based insulating fluid with a dielectric constant of 3.8, maintaining stable electrical performance across a temperature range of -40°C to +90°C and resisting oxidation for over 20 years.
Modular Design: Featuring tool-free connection mechanisms and adjustable clamping systems, these accessories accommodate cable diameters from 25–500 mm² and facilitate on-site installation in as little as 4 hours per joint, significantly minimizing maintenance-related downtime.
Renewable Energy Integration: Serve as critical links in connecting offshore wind farms to onshore grids, where their low-loss feature ensures maximum energy transmission from remote wind turbine arrays to mainland distribution networks. Notable installations include the UK’s Dogger Bank Wind Farm interconnection system.
Industrial Power Grids: Provide reliable power distribution in harsh industrial environments such as mining operations, oil refineries, and chemical plants, where their resistance to chemical corrosion and mechanical stress ensures long-term operational stability.
Cross-Border Transmission: Enable efficient HVDC links between nations, exemplified by their deployment in projects like the EuroAfrica Interconnector, which facilitates electricity exchange between Europe and Africa with minimal transmission losses.
Q: Are these accessories compatible with XLPE-insulated cables?
A: Yes, they are specifically engineered for seamless integration with XLPE and EPR-insulated cables, featuring matching insulation parameters and mechanical compatibility to ensure joint integrity.
Q: What certifications do they hold?
A: They fully comply with IEC 62067 (High-voltage direct current (HVDC) power transmission cables and accessories for rated voltages above 52 kV) and IEEE 48 standards, undergoing rigorous third-party testing to validate performance and safety.
Q: Can they operate in saltwater environments?
A: Absolutely. The 316L stainless steel housing combined with marine-grade fluoropolymer coatings creates a robust barrier against saltwater corrosion, making them ideal for offshore and coastal installations with a projected service life of over 30 years.
