Solar PV Step-Up Dry-Type Transformer | Inverter-to-Grid, 100-5000kVA

Cast-resin transformer for photovoltaic plants and non-linear inverter loads

HK$3600.00

Overview

Nelink solar step-up transformers couple PV inverters to the medium-voltage grid, stepping inverter output up to 10/33/35 kV. Designed for the harmonics, load cycling and compact skid environments of solar farms, the cast-resin design is safe for containerised inverter stations and pad-mounted skids.

Key Features

  • Optimised for inverter non-linear loads and harmonic tolerance

  • Cast-resin flame-retardant windings, ideal for compact PV skids/containers

  • High efficiency across variable solar load profile

  • Multiple voltage combinations for central and string inverters

  • AN/AF cooling with temperature monitoring
