Product Q&A

Q:What is the OLTC?

An on-load tap changer is a mechanism installed in power transformers that allows voltage regulation while the transformer remains energized and supplying load, without any interruption to power supply. Its primary role is to maintain a stable output voltage despite variations in input voltage or load conditions.

Q:What is the SVR?

SVR (Feeder Automatic Voltage Regulator) is an oil-immersed on-load tap-changing transformer series-installed in 6/10/35kV distribution feeders. It continuously tracks line voltage and automatically adjusts the on-load tap-changer position to regulate the transformation ratio, stabilizing the output voltage within the qualified range without supply interruption. Primarily used for voltage-drop compensation at the mid-to-rear section of radial feeders and voltage stabilization at substation outgo

Q:What information is required for ordering?

Required details include: 1. Model and rated capacity; 2. Rated voltage and regulation range; 3. Connection group (default Ya0); 4. Tap positions (7 or 9); 6. Transformer oil grade (25# or 45#); 7. GPRS remote communication module (optional); 8. Special environmental conditions.

Q:What are the lead times and payment terms?

Average lead time is one month during peak season and within 15 workdays during off-season. Payment terms are T/T. Minimum Order Quantity is 1.
