As a transformer radiator design engineer and production quality specialist, we have participated in the design, manufacturing and installation support of transformer cooling components for many years.
Through continuous project experience, we have found that:
A high-quality transformer radiator can only achieve its designed cooling performance when installation is completed correctly.
Transformer radiators are not simply external heat dissipation devices. They are an important part of the transformer oil circulation system.
Incorrect installation may lead to:
Therefore, professional installation requires strict control of:
In this guide, Radiastar engineers explain the complete installation process of fixed transformer radiators based on practical manufacturing and field experience.
A fixed transformer radiator is mainly used for:
Its main function is:
A typical radiator system includes:
The installation quality directly affects transformer cooling efficiency.
Before installation begins, professional engineers always perform four inspections:
Required tools usually include:
The lifting capacity must match radiator weight.
A single radiator unit normally weighs from:
100 kg to 500 kg or more
depending on:
Professional installation requires:
Correct bolt torque is essential for preventing:
Before lifting the radiator, engineers check:
Confirm:
The radiator must match the transformer tank interface.
Check:
The sealing surface must be:
Any damage may cause:
For ground-mounted radiators:
Engineers first install:
The support level should be checked to ensure:
Radiators must always be lifted from:
✓ Designed lifting lugs
Never lift from:
× Radiator fins
× Header pipes
× Thin panel structures
Improper lifting can cause:
During installation:
The radiator flange should align with transformer tank flange.
Engineers check:
Forced installation should never be used.
The sealing gasket is one of the most important components.
Professional installation requires:
Common gasket materials:
The gasket must:
Bolt tightening directly affects sealing reliability.
Bolts should be tightened using:
Diagonal Cross Pattern
Example:
For 8 bolts:
1 → 5 → 3 → 7 → 2 → 6 → 4 → 8This ensures:
Professional installation requires staged tightening.
50% designed torque
↓
80% designed torque
↓
100% designed torque
After tightening:
Engineers check:
For multiple radiator groups:
Additional components may include:
Important requirements:
Incorrect pipe installation may transfer mechanical stress to the radiator.
Quality inspection does not end after mechanical installation.
Radiastar recommends complete sealing verification.
Typical procedure:
Inspection points:
After oil filling:
Monitor:
A qualified installation should show:
✓ No oil leakage
✓ No abnormal pressure drop
✓ Stable operation
After installation, engineers check:
Including:
Check:
Air trapped inside radiator panels may reduce cooling performance.
During initial operation:
Monitor:
Under operating load:
Engineers evaluate:
Problem:
Old gasket loses elasticity.
Result:
Oil leakage.
Solution:
Always replace with new sealing gasket.
Problem:
Uneven pressure.
Result:
Flange leakage.
Solution:
Use calibrated torque tools.
Problem:
Incorrect flange positioning.
Result:
Mechanical stress.
Solution:
Adjust installation position instead of forcing bolts.
Problem:
Air remains inside radiator.
Result:
Reduced cooling efficiency.
Solution:
Proper venting during oil filling.
At Radiastar, transformer radiator manufacturing is based on:
We focus on:
Our production process covers:
Each radiator system is verified through:
A transformer radiator is a precision cooling component that requires professional installation.
Correct installation ensures:
✓ Reliable oil circulation

A transformer radiator removes heat generated by transformer oil and maintains safe operating temperature.
Installation includes positioning, flange connection, gasket installation, bolt tightening, pressure testing and commissioning.
Correct torque ensures uniform gasket compression and prevents oil leakage.
Common causes include:
Manufacturers use air pressure testing and oil leakage inspection.
