18 Nov Hiko & Sieyuan: Powering the Future of NZ Transmission
At Hiko Power Engineering, we believe solving tomorrow’s energy challenges starts with the partnerships we form today. That’s why our collaboration with Sieyuan Electric, a global leader in high-voltage technology, is more than a supply agreement — it’s a strategic advantage for New Zealand’s transmission future.
Together, we’re helping network operators move faster, with confidence.
Why It Matters
New Zealand’s transmission infrastructure is at a pivotal point — with decarbonisation targets, growing demand, and resilience expectations all placing new pressure on legacy assets.
The Hiko–Sieyuan alliance represents a smarter way forward: globally proven equipment, delivered locally with care, and supported by a team that understands New Zealand’s unique conditions.
CTs and CVTs Engineered for NZ Conditions
New Zealand’s power grid is evolving, and with it comes the need to upgrade ageing infrastructure. In many substations, aging oil-immersed transformers continue to present problems — from leaks and corrosion to labour-intensive maintenance and performance drift over time.
Sieyuan’s Current Transformer (CT)
Sieyuan’s CT range addresses these challenges directly:
- Fully sealed and corrosion-resistant
- Accurate and stable under fault conditions
These features make them ideal for coastal, high-humidity, and remote environments — delivering safer, more reliable performance in areas where downtime is not an option.
Sieyuan’s Capacitive Voltage Transformers (CVTs)
In regions with long, lightly loaded transmission lines, false relay trips and transient overvoltages caused by ferromagnetic resonance can be a thorn in the side of operators.
Enter Sieyuan’s Capacitive Voltage Transformers (CVTs):
- Built with proven damping technology to eliminate resonance
- Solid cast-porcelain design enhances seismic resilience
- Delivering accurate voltage measurement under dynamic conditions
Designed for the world’s most demanding grid environments, Sieyuans CVTs are a perfect fit for New Zealand’s seismically active and weather-exposed network.
Speed Where It Matters Most
While product integrity is non-negotiable, Hiko’s value doesn’t end at the spec sheet. Our integrated partnership with Sieyuan enables us to compress lead times, streamline logistics, and align production schedules — delivering transmission-grade equipment faster than traditional channels.
This speed is already making a difference, helping transmission projects stay ahead of schedule and avoid costly delays.
