Looking for a reliable wholesale LZZJ-10Q Current Transformer? Comewill factory delivers high-performance measurement solutions compliant with GB1208 standards. Our resin-insulated transformers support a wide primary current range (5-1000A) with FS<10 safety factors, ensuring long-term stability in demanding switchgear environments. Partner with Comewill for professional-grade electrical components that meet strict global engineering benchmarks.
The LZZJ-10Q Current Transformer is an indoor, reinforced-type current transformer. It utilizes a fully enclosed epoxy resin structure, integrating the primary and secondary windings with a high-permeability annular core.
Rated Insulation Level: 12/42/75kV (Ensuring safety against surges)
Accuracy Classes: 0.2S, 0.2, 0.5, 10P15 (Versatile for billing and protection)
Rated Current Ratio: 5A to 1000A / 5A (or 1A)
Standard Compliance: GB1208 & International IEC equivalents.
Insulation Integrity: The vacuum-cast epoxy housing provides an airtight seal against moisture, dust, and chemical contaminants, significantly extending the service life compared to traditional open-core models.
Dual-Frequency Compatibility: Optimized for both 50Hz and 60Hz systems, making it a versatile asset for international infrastructure projects.
High Short-Circuit Strength: With dynamic stability ratings reaching up to 90kA (for 1000/5A models), the LZZJ-10Q maintains structural integrity during fault conditions.
Low Phase Displacement: Designed with a 0.8 lagging power factor to ensure high-precision metering for energy billing.
The Comewill LZZJ-10Q is the "heart" of monitoring in several critical environments:
Industrial Switchgears: Integral for 10kV-12kV indoor vacuum circuit breaker units.
Energy Management: High-accuracy (0.2S class) metering for commercial building power consumption.
Relay Protection: Reliable signal output for overcurrent and short-circuit protection relays.

Q1: What is the difference between 0.2S and 0.5 accuracy classes?
A1:0.2S is a "special" high-precision class used for wide-load billing (accurate even at 1% of rated current), while 0.5 is the standard for general industrial measurement.
Q2: What makes epoxy resin casting better than traditional insulation?
A2: Epoxy casting seals the windings and core completely, offering superior moisture resistance, anti-pollution properties, and mechanical durability.
