JDZX vs Traditional Oil-Immersed VT: Why upgrade to dry type?

JDZX Dry Type VT

Epoxy Resin Cast Design

✓ Maintenance-free – No oil leakage risk
✓ Fire & explosion-proof – Safe for outdoor applications
✓ Anti-condensation – Epoxy resin casting withstands humidity
✓ Environmentally friendly – No oil contamination risk

Oil-Immersed VT

Conventional Oil Design

✓ Requires periodic oil testing
✓ Oil leakage & fire risk
✓ Heavier and bulkier
✓ Environmental disposal concerns

📍 Application & Selection Guide: Real-world scenarios

✅ Scenario 1: 35kV/36kV Substation (Metering & Protection)
Use JDZX series voltage transformer on incoming and outgoing feeders. It provides accurate voltage signals for energy metering (0.2/0.5 accuracy class) and protection relays (3P/6P). The outdoor dry type design withstands direct sunlight, rain, and temperature variations.

✅ Scenario 2: Wind/Solar Power Collection System
Renewable energy projects require reliable voltage monitoring at the point of interconnection. The JDZX outdoor dry type VT offers excellent anti-condensation performance, making it ideal for outdoor mounting in coastal or high-humidity environments.

✅ Scenario 3: Industrial Power Distribution (Mining, Cement, Steel)
For industrial facilities with harsh operating conditions, the epoxy resin cast voltage transformer provides maintenance-free operation, reducing downtime and operational costs.

Frequently Asked Questions

Q1: What is the difference between dry type and oil-immersed voltage transformers?
A: Dry type VTs use epoxy resin casting insulation – maintenance-free, fire-proof, and environmentally friendly. Oil-immersed VTs require periodic oil testing and pose leakage/fire risks. For outdoor 36kV applications, dry type is increasingly preferred.

Q2: What accuracy classes are available for the JDZX series?
A: Our 36kV outdoor dry type VTs offer accuracy class 0.2 (precision metering), 0.5 (general metering), 1 (industrial), 3P/6P (protection). We can customize based on your specific requirements.

Q3: What is the creepage distance of this voltage transformer?
A: The standard design provides ≥900mm creepage distance, suitable for Class II/III pollution environments. For high-altitude or heavy pollution areas, we can extend the creepage distance upon request.

Q4: Is this VT suitable for outdoor use in harsh weather conditions?
A: Yes. The JDZX series features IP54 rated secondary terminal box and epoxy resin casting that withstands direct sunlight, rain, condensation, and temperature variations from -40°C to +55°C.

Q5: Do you provide OEM/ODM service for voltage transformers?
A: Absolutely. We offer custom secondary voltage ratios, accuracy class configurations, special terminal boxes, and branded nameplates. Pre-production samples are available with a lead time of 7-10 days.
