Clean, Stable & Safe Power for Industrial and Commercial Applications
An isolation transformer is a specially designed transformer where the input (primary) and output (secondary) windings are completely electrically separated. This galvanic isolation ensures safe operation, reduces electrical noise, and protects sensitive equipment. ZHENGXI manufactures a full range of Single-phase isolation transformer and 3 phase isolation transformer products to meet global industrial and commercial power requirements.
An isolation transformer transfers power through magnetic induction rather than a direct electrical connection.Key advantages include:
Electrical Safety – The secondary circuit is “floating,” helping to prevent accidental electric shock when only one conductor is touched.
Noise & EMI Filtering – Reduces common-mode noise and blocks high-frequency harmonics, protecting precision instruments and control systems.
Voltage Stability – Helps maintain stable voltage when large loads start or stop, improving system reliability.
System Protection – Limits short-circuit current, prevents ground loops, and provides surge suppression.
These benefits make ZHENGXI isolation transformers ideal for medical equipment, CNC machinery, laboratories, data centers, audio/visual systems, and maintenance power supplies.

Core: Low-loss cold-rolled silicon steel or toroidal core
Cooling: Natural air (AN) or forced air (AF)
Optional electrostatic shield for superior noise attenuation
Custom engineering is available for special voltage ratios, shielding, or marine/harsh-environment enclosures.
Searching for the best isolation transformer price?Cost depends on several factors:
Power Rating (kVA) – Larger capacity requires more copper and steel.
Phase Type – Three-phase designs cost more than single-phase.
Voltage & Frequency – Special voltages or 400 Hz units increase complexity.
Enclosure & Protection – Higher IP ratings or weatherproof housings add cost.
Certifications & Testing – UL, CE, or medical-grade requirements require additional inspection.
Typical small Single-phase isolation transformer units start from a few hundred USD, while large custom 3 phase isolation transformer systems can reach several thousand USD.Contact ZHENGXI for a fast, no-obligation quote tailored to your exact specifications.

Q1: What is the difference between a Single-phase isolation transformer and a 3 phase isolation transformer?A Single-phase isolation transformer handles single-line AC loads (typical for residential or small commercial use). A 3 phase isolation transformer is designed for industrial facilities and heavy equipment that require three-phase power for higher efficiency and capacity.
Q2: Does an isolation transformer completely eliminate electric shock risk?It greatly reduces the chance of shock when only one conductor is touched because the secondary circuit floats relative to ground. However, touching both secondary conductors simultaneously can still cause electric shock. Proper safety practices are always required.
Q3: How do I get an accurate isolation transformer price?Provide details such as kVA rating, input/output voltage, phase type, enclosure requirements, and any necessary certifications. ZHENGXI will then supply a detailed quotation with lead time and shipping options.
