Advantages of 35kV Current Transformer Compared with Other Voltage Levels
Optimized for Distribution-Level Systems
Compared with high-voltage (126kV and above) current transformers, the 35kV model is specifically designed for distribution networks, offering a more compact structure and cost-efficient solution.
Faster Delivery and Easier Deployment
Due to standardized design and widely used application scenarios, the 35kV Current Transformer typically benefits from shorter production and delivery cycles compared with extra-high-voltage equipment.
FAQ – 35kV Current Transformer
1. What is the typical lead time for a 35kV Current Transformer?
For standard configurations, the lead time of a 35kV Current Transformer is typically 2–4 weeks. For customized designs or project-specific requirements such as special accuracy classes, multiple secondary windings, or non-standard mounting structures, the delivery time may extend to 4–8 weeks depending on engineering confirmation and production schedule.
2. Can the 35kV Current Transformer be used in both switchgear and outdoor substations?
Yes. The 35kV Current Transformer is designed for flexible installation and can be used in metal-clad switchgear, compact substations, and outdoor substations. However, the insulation structure and housing type may vary depending on indoor or outdoor application requirements.
3. What accuracy classes are typically available for 35kV Current Transformer?
The 35kV Current Transformer commonly supports multiple accuracy classes for metering and protection, such as 0.2, 0.5 for metering and 5P10, 10P10 for protection. The exact configuration depends on system requirements and relay protection design.
4. How is the 35kV Current Transformer different from higher-voltage CTs in practical application?
Compared with 126kV and above current transformers, the 35kV model is mainly used in distribution-level substations, featuring a more compact structure, easier installation, and lower overall system cost. It is typically used in industrial plants, commercial power distribution, and regional substations rather than transmission-level grids.
