Five steps to specify your run
A configuration summary is generated as you go. It travels with your inquiry, saving a round of confirmation.
Build details
Systems have been in service for decades, and the failure points are always the same few: poor busbar contact, water ingress at the door seal, high temperature rise in the correction cabinet, and mis-phased outgoing feeders. The six hard rules below are written for exactly these points — every cabinet can be traced to them.
IK10 comes from structure, not plate thickness
2.0 mm door panel + vertical reinforcing rib liner — impact energy disperses along the ribs. Simply stacking plate thickness to 3 mm is dead weight; the rib structure is the real answer to 20 J.
Still serviceable after a hit
IK10 acceptance is not just about surviving the strike: after a 20 J impact, the door must still open normally and the lock must still function. A cabinet that cannot be opened after one impact is a dead cabinet no matter how high its protection rating.
No removable pin on the outside
The hinge pin is internal — nothing removable can be reached from outside the cabinet. An exposed pin can be knocked out with one strike, and the door comes off.
The keyhole is not the weak point
The lock cylinder bore is lined with a hardened anti-drill shield, and the cylinder sits deep. Three-point compression leaves a pry bar no fulcrum. The lock position is always the first point of attack on a cabinet — that is where material matters most.
Nothing can be pushed in
Concealed bottom ventilation + anti-tamper mesh. In public locations, objects pushed into a cabinet cause more damage (short circuit and fire) than a forced door.
Reports provided per project
IK10 is delivered to the design specification; third-party test reports are provided per project requirements. Test lead time and cost are stated clearly at the project stage — no surprises after the fact.
Photos & enclosure construction
Below are photos taken in our own shop — from the complete unit down to the internal busbars and secondary wiring. Every build detail can be checked item by item.
Image key: 01–05 are shop photos (the numbers match the shot list). The line drawing shows the front elevation of the enclosure; dimensions match the specification table above.
Where these cabinets go
These are the routine applications — we can talk scheme and configuration directly. For the industry view, see the industry pages.
EV charging station cabinet
Power and control cabinets for street and parking lot charging equipment, built to take impact and resist prying.
Transit platforms and shelters
Information and control equipment for bus platforms, in high-foot-traffic locations.
Venues and plazas
Open-site installation of lighting and audio control cabinets.
Open industrial sites
Pump control and lighting cabinets in areas without perimeter fencing, unattended at night.
Park water supply and drainage
Landscape-area water supply and drainage control cabinet, finished to match the surrounding architectural coating.
Retrofit & reinforcement
Existing public-area enclosures re-skinned to an IK10 structure, reusing the existing foundation.

Six questions procurement and electrical engineers ask most
What does IK10 actually mean?
The highest class of external mechanical impact protection under IEC 62262 / GB/T 20138: a 5 kg striker dropped from 0.4 m delivers 20 J of impact energy to the enclosure surface, and protection and safety performance must not fail. In plain terms: hit it with a hammer and the cabinet keeps working.
Can a cabinet be IK10 and IP65 at the same time?
Yes. IK covers impact resistance and IP covers dust and water ingress — two independent ratings. Public outdoor installations usually need both, with the structure and test plan set by the project specification.
Do you have an IK10 certificate?
We design and deliver to the IK10 rating, and third-party test reports are provided to project requirements — testing requires sample submission and involves lead time and cost. If your project needs it, say so at the quotation stage and we will arrange it accordingly.
Is the price much higher than a standard enclosure?
The structural differences are door stiffening ribs, a recessed lock, internal pin hinges and tamper-resistant fasteners, which puts a same-size unit one cost tier above a standard enclosure. There is no need for IK10 in a closed electrical room with no public access — spend the money where it counts.
Can the viewing window be glass?
Viewing windows on an IK10 cabinet use PC (polycarbonate), not glass — glass cannot reach the required impact rating on its own and would be the weak point in an otherwise IK10 enclosure.
If it gets dented, can it be repaired?
The door stiffening ribs absorb most of the impact, and standard parts (door, lock, hinges) can be replaced individually — that is the value of the "door opens after impact" design: replace the damaged part, leave the enclosure alone.
