Custom Engraved Utility & Substation Identification
Engraved identification for utility infrastructure and substation installations. Panel labels, arc flash labels, equipment identification, valve tags, and warning placards. Manufactured every business day for California utilities including PG&E.
25+ years of engraved utility and substation identification.
We have manufactured engraved identification for utility infrastructure since 1982. We've been PG&E's phenolic tag and label supplier for over 25 years, producing substation identification every business day — panel labels, arc flash labels, equipment identification, warning placards, and valve tags in both phenolic and metal.
Our engraved identification serves utility contractors, facility teams, and electrical engineers working on substation projects throughout California and nationwide. We manufacture from your project specifications, drawings, and label schedules — every order built to survive the utility infrastructure environment where it will live.
Substation identification produced every business day.
We produce engraved compliance identification every business day from our Chico, California facility. Substation work runs weekly, if not daily — for PG&E and other California utilities. We manufacture panel labels, arc flash labels, equipment identification, valve tags, and warning placards to your project specifications.
Utility work is core to what we do. Our production capacity supports project-scale identification packages, ongoing utility programs, and single-piece replacement orders.

Engraved High Voltage Warning Labels
We manufacture engraved high voltage warning labels for utility substations, generation facilities, industrial installations, and commercial electrical services. Our warning labels are engraved from durable phenolic or metal materials for long-term outdoor exposure — sun, weather, and physical wear are conditions the material is selected to handle.
High voltage warning labels we manufacture include:
- High-voltage danger placards per ANSI Z535.4 formats
- Clearance distance warnings
- Arc flash labels per NFPA 70E — see engraved arc flash labels
- Substation entrance warning signs at PG&E's standard 14 inch by 7 inch format
- Equipment-specific voltage identification (kV ratings, phase identification)
- Custom warning placards per your project specifications and label schedules
Our warning labels are manufactured from your project's drawings, specifications, and label schedules. We work with utility engineering departments, electrical contractors, and facility teams on new construction, retrofits, and repair replacements.
For reflective aluminum warning signs, vinyl adhesive high-voltage labels, stock printed products, or APWA burial warning tape, we recommend working with your project's signage supplier or specialty utility sign manufacturer — our capability is engraved identification for the electrical equipment and installation.
PG&E Substation Signage Standards
We have served as PG&E's phenolic tag and label supplier for over 25 years, manufacturing engraved substation identification for PG&E work weekly, if not daily. Our identification is manufactured consistent with PG&E's documented standards for substation signage and equipment identification.
PG&E-documented standards our engraved identification supports:
- PG&E TD-1013P-05 — PG&E Substation Signage for Third-Party Interconnections (governs substation signage for interconnections to the PG&E system)
- PG&E Engineering Standard 034851 — Switch and platform construction reference
- PG&E Engineering Design Standard 454092 — Switch number target plate bracket
- PG&E System Operations switch numbering — PG&E assigns primary disconnect switch numbers; we manufacture engraved switch number plates consistent with PG&E-assigned numbers
- PG&E standard substation location signs — 14 inches wide by 7 inches high, posted at each entrance to the substation facility
We manufacture from PG&E-approved drawings, specifications, and label schedules provided by contractors, engineers, and PG&E project teams. For third-party transmission interconnection projects, we can produce identification consistent with the substation signage requirements in TD-1013P-05.
Confirm applicability of specific PG&E standards to your project with your PG&E project engineer or the applicable PG&E System Operations contact.
Utility Identification Categories We Manufacture
Utility and substation projects manage identification across many equipment categories. We manufacture engraved identification for:
- Feeder identification — Circuit and feeder identification per utility naming schemas
- Bay and section identification — Substation bay identification, bus section identification
- Bus identification — Main bus, transfer bus, tie bus identification
- Transformer identification — Transformer nameplates, kVA ratings, cooling class markings, tap position identification
- Switch and breaker identification — Switch number plates per PG&E System Operations assignments, breaker identification, disconnect labels
- Panel identification — Panel labels per NEC Article 408, control panel identification, relay panel identification
- Cabinet and enclosure identification — Cabinet nameplates, enclosure warning placards, access identification
- Function and location codes — Function code identification per utility engineering schemas
- Substation location signs — Entrance signs, restricted access signs, ownership identification
- Warning placards — High-voltage warnings, clearance distance warnings, arc flash labels per NFPA 70E
All identification is manufactured from your project's drawings, specifications, label schedules, and applicable utility engineering standards. For utility contractors and engineers working on multi-substation projects, we can maintain your specifications on file for consistent identification across future work.
What We Do Not Manufacture
We manufacture engraved identification. For a complete utility or substation signage plan, other product categories may be required — we recommend working with a specialty utility sign supplier for:
- Reflective aluminum signs (ANSI/OSHA reflective safety signs, NEMA reflective high-visibility warning signs)
- Vinyl adhesive labels and decals (including pad-mounted transformer decals, "Mr. Ouch" adhesive labels)
- APWA color-coded burial warning tape (red for electric, orange for telecom/fiber)
- Burial markers, soil posts, and underground asset markers
- Stock printed utility signs and general reflective safety products
Our capability is engraved identification manufactured to your project specifications — engraved from durable phenolic or metal materials for the electrical equipment, structural identification, and warning placards that require long-term legibility at substations, generation facilities, and industrial installations.
