Wired Industries is an operating division of Sustainable Infrastructure Group Ltd., an Alberta group whose companies work remote sites, pipeline right-of-way and heavy civil ground. It trades as SIG Wired Industries. It manufactures the wiring harnesses and wiring systems that autonomous and uncrewed machines are assembled around, and the pre-wired power and control packages that go to ground where there is nobody to wire them. It builds to your issued drawing set or interface specification, and it returns the manufacturing detail.
Why this trade needs a harness house
Remote work teaches one lesson before any other. Whatever arrives has to work when it arrives, because the person who can fix it is a day away and the part to fix it with is further. A pipeline right-of-way is a site that moves every day. The machines on it run in dust, in vibration and in cold, and every wire on them flexes, chafes and soaks. The wiring that was built on the machine, in the field, from what was on the truck, is the wiring that fails first, and it fails as an intermittent that costs a machine-day to find and a truck roll to fix.
The wiring that lasts on the right-of-way is wiring built somewhere it could be measured, tested and labelled before it ever saw the machine: on a bench, from a drawing, by a person whose only job that day was the loom. Machines working that ground need that kind of wiring, and sites like those need plant landed complete. That is the work this division exists to do.
Heavy civil also teaches what a harness house needs to know about drawings. A civil crew does not pour to a sketch. It pours to a signed set, and if the set is wrong the crew stops and asks, because the concrete does not care what anybody meant. Wired Industries works the same way. Nothing is fabricated until the drawing is signed. The copper does not care what anybody meant either.
Where a machine programme owns the design
Where a harness belongs to a machine programme, the relationship needs stating exactly, because harness houses and machine programmes get it wrong in both directions. Where no programme is involved, the same rule applies to whoever holds the design.
The machine programme owns the design and the drawing master. It owns the safety case, the circuit topology, the interface with everything the harness lands on, and the decision about what changes and when. Wired Industries builds the full shop pack against that issued set: the takeoff, the cut list, the termination schedule, the formboard layout, the material list with the certification of every component on it, the test record and the build record. That pack is owed back to the programme. It describes their machine, so it is theirs, and a programme that does not hold its own manufacturing detail cannot have the harness built anywhere else, cannot audit it, and cannot revise it with any confidence.
We build to a customer's issued set and we return the manufacturing detail. That is the whole of it. We do not take design authority we have not been given, and we do not hold on to what we have learned about your harness as the reason you have to come back.
A drawing from inside the group is a drawing. It goes through the same intake, the same board, the same tests and the same record as yours, and it waits for its signature like any other.
Safety circuits never share a bundle, a splice or a shell with power.
Who the shop is for
- The shop is for a machine programme that has a drawing set and needs it built.
- It is for an integrator putting an autonomy loom onto a machine that was built for a person.
- It is for a research or training group that needs a capture rig wired to nothing on the host machine.
- It is for a site owner who needs power and control plant landed complete on ground where there is no labour to wire it.
- What each of those needs to bring, and what each gets back, is on who it is for.
How the shop is run
The shop runs on the drawing. You issue the set or the interface specification. We take it off conductor by conductor and termination by termination, and where the set is silent we write the question down and send it back rather than filling the gap from experience. The answer goes into a signed revision. Then the takeoff becomes a material order, a cut list, a termination schedule and a formboard laid out from the drawing at full size, and the build starts. There is one board per drawing revision. When the revision changes the board is laid again, not patched, because a patched board carries two revisions at once and nobody can say afterwards which one the harness on it matches.
Material is sourced against the takeoff, and only against the takeoff. The components we specify carry their own certification. The approval route for a finished, project-specific assembly is confirmed with the certifying body for that assembly before it is built, and we tell you where yours sits before we build it, not after. CSA governs and the Canadian Electrical Code applies to anything built for installation in Canada. We do not build to another country's framework and hope it maps across.
On the board, every conductor is cut to the drawing, marked with its circuit identity at both ends and at every break-out, and terminated with the tool the terminal maker specified for that terminal. Safety circuits never share a bundle, a splice or a shell with power. Shields are grounded where the drawing says and nowhere else. Every finished assembly is tested before it leaves: continuity, to prove that every pin lands where the drawing says; isolation, to prove that circuits which must never meet are in fact separate; and a sample pull on the crimps, to prove that the joint is a joint. What each test proved goes on the record with the drawing revision the assembly was built to, and the record travels with the harness.
One person is responsible for each build from takeoff to pack, and that person signs the record. A second person checks the board against the drawing before the first conductor is laid, and checks the finished assembly against the board before it is packed. Nobody witnesses the test of an assembly they terminated, so the test is witnessed by whichever of the two did not. Neither check is a formality. A board laid to the wrong revision produces a harness that is perfect and wrong, and the only place to catch it is before the copper is cut.
A value nobody measured never reaches a wire. A length comes off the drawing, or off a walk of the machine. A torque comes off the connector's own data. A crimp height comes off the terminal's specification and a checked tool. Nothing comes from memory, from the last job or from a brochure.
What to send, and what comes back, is on how to engage. Where to send it is on contact. The four lines are UAV, autonomy, training systems and industrial plant, and the argument behind all four is on the seam.
What we refuse
- We will not cut to an unsigned drawing.
- We will not guess a length, a gauge, a pin or a torque and put it on a wire.
- We will not put a safety circuit in with power, whatever it would save in connectors or in days.
- We will not take design authority we have not been given, and we will not keep manufacturing detail from the programme that owns the design.
- We will not state a test value for a class of assembly; the value is set on your assembly, by the engineer responsible for it, against your specification, or it is not stated.
- We will not publish a figure that belongs to a programme that is not ours.
