• Compliant Standards:

GB/T 20840.1, IEC 61869-1; GB/T 20840.2, IEC 61869-2; GB/T 20840.3, IEC 61869-3, and special customer requirements.

• Structural Overview:

1. Voltage Transformer: Manufactured using epoxy resin casting, with the coil fully enclosed within the body. The primary high-voltage terminal is led out through a standard cone. Some products are equipped with internal high-voltage fuses that are detachable and replaceable. The secondary output is provided in forms such as cable leads or terminal boxes for user convenience.
2. Post-type Current Transformer: Manufactured using epoxy resin casting, designed as a single-phase structure. The transformer is installed upright in the gas chamber, with a sealed slot at the secondary terminal.

• Product Features:

1. Voltage Transformer: Features a compact structure, low partial discharge, and a metal shielding layer on the outer surface. During operation, it is grounded through connection with the mounting plate and base plate, achieving full shielding to effectively avoid electric field interference and enhance operational stability.
2. Current Transformer: Features a compact structure, high thermal stability, low partial discharge, and stable and reliable secondary sealing.

• Application Fields:

Power transmission and distribution substations, renewable energy generation, offshore platforms, petrochemical industry, electrified railways (traction substations/AT stations/switching stations/sectioning posts), intelligent grid distribution networks, urban rail transit (subways, light rails, intercity railways), and other fields.
