Product Overview

The SC(B)18 (SC18-NX1) Grade 1 dry-type transformer is developed to GB 20052-2020. New materials and processes plus optimized core and coil design bring no-load loss more than 40% below SC(B)10, with every loss figure lower than the SC(B)13 series. Noise is 20% lower on average than JB/T 10088-2016.

Key Features

Excellent energy savings, economical operation, maintenance-free;
Vacuum-pressure casting, low partial discharge; flame-retardant, explosion-proof, moisture- and dust-proof;
High dynamic and thermal stability with strong short-circuit and lightning-impulse withstand;
Optional IP20/IP23 enclosures, temperature control and axial fans for extra capacity.

Technical Parameters

Voltage combination: HV 10 (6.3/6) kV ±5% or ±2×2.5%, LV 0.4kV; connection group Yyn0 or Dyn11.
