Transformer Packaging
& Export Crating

Power and distribution transformers carry concentrated weight, fragile bushings, and oil or nitrogen-filled internals that punish careless handling. BENZ Packaging preserves, crates and ships transformers from a few hundred kVA to 120-ton power units, sealed against moisture and braced for the worst a sea voyage can do, on site at your works and certified for export to 100+ countries.

The Challenge

Why Transformers Arrive Damaged

A transformer concentrates enormous mass over a small footprint, so the first risk is purely mechanical: an off-centre lift, an unbraced core, or a skid that flexes will crack welds, shift the core-and-coil assembly and shear the very bushings that make the unit serviceable. The second risk is moisture. Transformer insulation is hygroscopic; a winding that absorbs water during a six-week ocean transit can fail its dielectric test on arrival even though it left the factory perfect. Bushings, radiators, conservators and the control cabinet each add fragile, protruding surfaces that bare handling destroys.

The third risk is documentation. A transformer shipped on untreated timber is stopped at the destination port for want of an ISPM-15 stamp, and an oil-filled or nitrogen-charged unit shipped without the correct state declaration invites customs and safety problems. BENZ engineers the whole chain: core and winding immobilisation, VCI and desiccant moisture control, individually crated bushings and accessories, heat-treated seaworthy skidding rated to the unit's true weight, and the export documentation that keeps the consignment moving.

What We Protect on a Transformer

Each assembly is addressed individually, not wrapped as one anonymous block.

Core & Winding Assembly
Immobilised against shift and shock; VCI vapour protection inside the tank and against insulation moisture pickup.
Bushings
Removed where required and individually crated with cushioned, sealed protection against impact and contamination.
Radiators & Conservator
Nozzle and flange sealing, separate crating of detachable radiators, and VCI on internal carbon-steel surfaces.
Oil / Nitrogen State
Correct handling and declaration of oil-filled, oil-drained or nitrogen-charged transport states for safe, compliant shipping.
Tap Changer & Control Cabinet
Moisture-barrier protection of electrical controls and the OLTC, kept dry with desiccant inside sealed enclosures.
Base, Skid & Lifting
Heat-treated skid engineered to true weight and centre of gravity, with marked, rated lifting and jacking points.

How We Package a Transformer for Export

Performed on site at your works by a BENZ team with all materials, tooling and lifting equipment.

01

Survey & Preparation

Assessment of weight, centre of gravity, transport state and detachable accessories; removal and labelling of bushings, radiators and fittings where required.

02

Moisture & VCI Protection

VCI vapour-phase inhibition to MIL-PRF-3420H on internal and external steel, plus MIL-D-3464E desiccant inside sealed enclosures to hold insulation and controls below the corrosion and dielectric-failure threshold.

03

Immobilisation & Cushioning

Core-and-coil and all moving assemblies braced; shock and vibration isolation calculated for road and sea handling and stacking loads.

04

Barrier & Accessory Crating

Aluminium barrier bagging for long or humid transits; bushings, radiators and controls individually crated and cushioned.

05

ISPM-15 Seaworthy Skidding

Heat-treated, ISPM-15-stamped skid and crate built to true weight, with rated lifting and jacking points for forklift and crane handling.

06

Loading & Documentation

Lashing and load securing in the container, plus packing list, heat-treatment certificate, transport-state declaration and handling marks for clean customs clearance.
