Product Introduction
1.35kV Outdoor Current Transformer: Reliable Power Measurement for Harsh Environments
When you need precision current measurement in demanding outdoor settings, our 35kV Outdoor Current Transformer delivers unmatched reliability. Designed for power grids, renewable energy plants, and industrial complexes, this high-voltage instrument combines epoxy resin casting with silicone rubber insulation to withstand extreme temperatures (-40°C to +70°C), UV exposure, and pollution. With 0.2/0.5 accuracy classes for metering and 5P/10P for protection, it ensures grid stability while reducing lifecycle costs.

3.Key Features & Advantages
1. Extreme Environment Resilience
The composite insulation system (epoxy resin + silicone rubber) prevents moisture ingress and corona discharge, even in coastal or high-pollution areas.
2. Dynamic-Thermal Stability
Withstands 30kA short-circuit currents for 1 second – critical for fault protection in wind farms and solar plants.
3. Low Maintenance Design
Fully enclosed, corrosion-resistant construction eliminates routine cleaning. Maintenance intervals exceed 10 years.
4. Smart Grid Ready
Optional IoT sensors enable real-time health monitoring (partial discharge, temperature) for predictive maintenance.
4.Typical Applications
Be used in a wide range of industries.
Industrial Plants
Eliminate power factor penalties in CNC machines and assembly lines while handling surge currents up to 100x rated capacity.
Substation
Stabilizes substation voltage against harmonics and intermittent generation from renewable inverters.
Commercial Buildings
Retrofit aging systems in hospitals or malls with silent (<45dB), flame-retardant capacitors that meet NFPA 70 fire codes.
5.How It Works？
The 35kV Outdoor Current Transformer steps down high primary currents (600-800A) to standardized secondary outputs (1A/5A) via electromagnetic induction. Its cast resin insulation ensures zero oil leakage risks, while multiple tapped windings allow ratio adjustments without physical disassembly.

8.FAQs
Q: Does it comply with IEC 61869-2 for digital substations?
Yes, we offer models with IEC 61850-9-2LE digital outputs.
Q: Can it operate in desert climates?
Absolutely – the silicone rubber housing resists sand abrasion and 55°C ambient heat.
Q: What’s the lead time for 1000-unit orders?
Standard configurations ship in 4 weeks; customized designs take 6-8 weeks.
Q: How do you prevent accuracy drift?
Our proprietary annealing process stabilizes the core’s magnetic properties for ±0.1% precision over 30 years.
