FAQs.

What signage is required in an electrical substation?

A typical substation requires danger signs at all entry points, equipment identification plates on transformers and switchgear, cable identification labels, earth point markers, procedure signs for switching and isolation, and switchgear labels. Requirements vary by site, with some network operators specifying additional items.

How long do substation signs last outdoors?

Standard safety signs begin to fade within a few years — red colours degrade first. Identimark signs are field-proven for 32+ years with full colour and readability. Backed by a lifetime guarantee.

Can you supply a complete substation signage package?

Yes. We are a single-source supplier for all substation identification — from perimeter danger signs to individual switchgear labels. We manufacture everything in-house and work from your signage schedule or specification.

What causes safety signs to fail in substations?

Sun damage is the primary cause. Prolonged exposure breaks down colours and materials, causing fading and cracking. Our signage is built with a through-body UV-blocking material designed to resist sun damage, temperature swings, and chemical exposure.

Do you work to specific network operator requirements?

Yes. Many network operators have their own signage specifications that go beyond the baseline. We manufacture to those requirements and can work directly from your specification or schedule.
