Sparky Sam
De-energised cleaning of switchgear, motors and substation equipment within your isolation window. No water, no drying time, IR readings preserved.
Sparky Sam — typical environment
De-energised cleaning of switchgear, motors and substation equipment within your isolation window. No water, no drying time, IR readings preserved.
Your switchgear, motors and substation equipment need cleaning — but shutdown costs are eye-watering, and water or solvent introduces risk to insulation and adds drying time before you can re-energise. Compressed air just drives contamination deeper. We only clean equipment your licensed electrical worker has isolated and proven de-energised, with our own lock and tag on the isolation point. Dry ice is non-conductive and non-abrasive, so there's no drying time within that window: insulation resistance preserved, cooling fins clean, operating temperatures lower, asset life extended. We work to your safety case, with your electrical authority, and produce per-asset IR-test documentation for your asset register.
Pain points we hear most
- Shutdowns for cleaning cost six figures in lost capacity
- Water and solvent compromise insulation health
- Compressed air relocates dust rather than removing it
- Asset register documentation requires structured records
- High-voltage operator coordination is a workflow constraint
What you're looking for
- De-energised cleaning turnaround within a scheduled outage
- IR-test before/after for asset register
- Coordination with HV authority
- Per-asset documentation (photo log + IR readings)
- Annual scheduling commitment
Is dry ice cleaning right for this asset?
A safety-first decision tree for electrical maintenance. We do not clean energised equipment — isolation and proving-dead by a licensed electrical worker is a precondition, not an option.

Does dust loading correlate with insulation-resistance reduction (annual IR test trending down)?
?
Will an outage be scheduled anyway for other maintenance?
✓
Dry ice clean during scheduled outage, with IR-test pre/post
Isolated and proven dead by your licensed electrician, with our own lock and tag on the isolation point — we do not offer live cleaning at any dust-loading level. No water, no drying time, so the outage window is as short as possible. IR readings improve measurably. Standard for MV switchgear and substations. Annual programme typical.
See this service → ✓
Monitor and re-evaluate
If IR readings are stable, defer cleaning. Re-test in 12 months and revisit.
✓
Defer until next maintenance window
Plan dry ice cleaning into the next scheduled outage rather than triggering one for cleaning alone.
Common questions
What customers like you ask before they book
Can you really clean MV switchgear live?
No. We only blast switchgear that has been isolated and proven de-energised by a licensed electrical worker, with our own lock and tag on the isolation point — that's a WHS-regulation requirement (model reg 154), not a preference. We work to the asset owner's electrical authority throughout. Where dry ice earns its keep is inside that outage: no water, no solvent, no drying time, so the shutdown is as short as it can be.
How is this different from compressed air?
Compressed air relocates contamination, often driving it deeper into insulation. Dry ice physically removes contamination through thermal shock + kinetic impact + vapour expansion. IR readings actually improve after dry ice cleaning; they typically don't after compressed air.
What documentation will I get?
Per-asset photo log (pre/during/post), IR test sheet with before/after readings, cleaning record with operator sign-off. Suitable for asset register. Delivered as a structured PDF within 24 hours of close-out.
Are your operators electrically qualified?
Our crew works to your safety case. For HV work, we coordinate with your electrical authority and licensed HV operators. We don't operate beyond the agreed scope.

Sparky's FAQs
How much will IR improve after cleaning?
It depends how much of the leakage path was contamination rather than insulation condition, so we don't quote an expected percentage up front. We IR-test before and after and give you both readings — on your own asset, that pair is the only number worth having. Where contamination was low the reading may hold steady rather than improve, which still confirms the clean didn't degrade the asset.
Do you carry MV-specific safety case documentation?
We work to your safety case. We can provide template procedure documents, RA frameworks and PPE specifications for your authority's review and adoption.
Is this approved for substation use?
Used routinely in substation environments under appropriate procedures. Each site has its own safety case — we work to yours.
Will it damage motor windings?
No. Pressure tuned for windings (60-80 PSI typical) — far below what would damage insulation. Pellets sublimate before they can abrade.
