The Future of Medium Voltage Technology: Shielded Solid Insulated Systems (2SIS)

Blog Content:

Medium voltage switchgear has long been the backbone of electrical distribution systems worldwide. From substations to industrial facilities, the need for safe, reliable, and compact solutions has never been greater. Degatech Electric Co. Ltd. has pioneered the next generation of medium voltage switchgear with its Shielded Solid Insulated System (2SIS), setting new benchmarks for safety, efficiency, and operational reliability.

Historically, medium voltage switchgear designs relied heavily on air-insulated and metal-clad configurations. These systems provided acceptable performance but were constrained by size, maintenance needs, and environmental exposure risks. Over the past decade, as industrial applications demanded higher power density and stringent safety standards, it became clear that a new approach was necessary.

Degatech’s 2SIS technology addresses these challenges by integrating molded epoxy insulation and a conductive ground shield around each phase. This approach reduces phase-to-phase interaction, minimizes arc flash potential, and eliminates exposed live parts. The result is a compact, high-performance switchgear solution suitable for a wide range of applications.

Enhanced Safety and Reliability

Safety remains the most critical factor in medium voltage switchgear design. The 2SIS design inherently improves operator protection by maintaining all internal components at ground potential. Coupled with interlocked access panels and minimal maintenance requirements, the risk of accidental contact or electrical faults is drastically reduced.

By using a shielded solid insulation system, Degatech ensures that the switchgear’s dielectric integrity is preserved for longer operational cycles. Common failure causes, such as dust accumulation, moisture ingress, or mechanical damage during maintenance, are mitigated through robust construction and advanced insulation materials.

Efficiency and Space Optimization

One of the key advantages of 2SIS switchgear is its reduced footprint. Traditional metal-clad systems often require large rooms and significant clearance for safe operation. With 2SIS, equipment depth and width are reduced by up to 60%, allowing for flexible installation in constrained electrical rooms without compromising performance.

This compact design does not compromise thermal management. Degatech has integrated efficient ventilation and heat dissipation paths, ensuring that high-current components operate within safe temperature ranges. The result is a system that can handle high loads reliably while occupying minimal floor space.

Integration and Monitoring

Modern facilities demand switchgear that can integrate seamlessly with control and monitoring systems. Degatech 2SIS units support a wide range of automation interfaces, allowing real-time monitoring of load conditions, fault diagnostics, and predictive maintenance planning. By reducing unplanned downtime, facilities can maintain higher operational efficiency.

Degatech Electric Co. Ltd. also offers customization options for its 2SIS systems, including modular layouts, integrated vacuum circuit breakers, and variable current ratings. This flexibility ensures that clients receive solutions tailored to their specific load profiles and operational requirements.

Sustainability and Lifecycle Benefits

Beyond safety and efficiency, the 2SIS technology is designed with sustainability in mind. The robust insulation and reduced maintenance cycles extend the lifecycle of the switchgear, minimizing material consumption and replacement needs. Degatech also incorporates environmentally responsible manufacturing practices, aligning with global energy efficiency standards.

For facilities aiming to modernize their electrical distribution systems, Degatech’s 2SIS switchgear provides a long-term, reliable, and eco-friendly solution. Learn more about how this innovative technology can enhance your infrastructure at https://chinadegatech.com/.
