ISO-COAT® – A New Standard for Cable Longevity.
Designed to be Played, Built For a Lifetime®
Our stake in the ground — A promise to you.
From humble beginnings — as Voltage Cable Co.® started to establish itself in the guitar cable market, we made a very clear decision: to set a new standard for what durability is and means, and to manufacture guitar cables that are not only inspiring to use, but that actually last a lifetime.
What truly matters to us is that you, the artist, receive a product that can stand the test of time — a product we can back with 100% confidence. We want our customers to focus on playing, not worrying about gear failure. That’s why our attention has been on developing the best-sounding, reliable guitar cables money can buy.
It all starts with high-quality components and the skilled handmade work. Our highly experienced cable technicians use Quad Eutectic silver solder, ensuring oxygen-free connections for maximum signal integrity and strength — along with a rigorously tested quality control program that ensures every cable shipping from Sydney has been approved.
Using quality components is one thing — and yes, they definitely matter. But ignoring the real reasons cables fail? That’s not doing the industry, or our artists, any justice.
For the last 4 years, we have been working tirelessly diagnosing, developing, testing, and innovating our way to a solution for this decades-old, industry-known problem we all know as cable failure.
"Every company wants return customers. We want lifetime customers using our lifetime products."
Introducing ISO-COAT® – The First and Only Lifetime Hermetic Seal for Instrument Cables. (Pat. Pending)
With our hard work and 45+ years of hands-on experience — on the bench, in the studio, and on stage — we’ve encountered every type of cable failure imaginable. So, sticking to our core beliefs at Voltage, we invented ISO-COAT® — a patent-pending, world-first solution to eliminate cable failure at its source.
ISO-COAT® hermetically seals the entire cable assembly, preventing oxidation, corrosion, and atmospheric attack — the leading causes of signal loss, sonic degradation, and cable failure. Designed for any gig, any climate, anywhere, we can proudly say this is our stake in the ground as a boutique Australian company stepping up to deliver guitarists of the world a product that actually does what it says on the box.
Every guitar cable leaving our warehouse in Sydney now comes protected with ISO-COAT® — and a hand-stamped wax seal authenticity card symbolising our guarantee and innovation to you.
For guitarists who demand genuine lifetime durability from their gear and consistent connection to their music, Voltage Cable Co. is here to provide that small but crucial link between the artist and the expression.

Keine toten Kabel mehr. Einführung von ISO-COAT®
Für jeden Auftritt, jedes Klima und jeden Ort. Diese einzigartige, zum Patent angemeldete hermetische Versiegelung verhindert Korrosion und Oxidation – lautlose Klangkiller, die Kabel und Ihren Sound zerstören.
Die Schwachstelle
Jedes Gitarrenkabel hat eine Schwachstelle – den Anschlusspunkt. Ohne Schutz greifen Feuchtigkeit und Luft das Kupfer langsam an , was zu Knistern, Signalverlust und einem Totalausfall führt , wenn man es am wenigsten erwartet.
Die Wissenschaft des Verfalls: Was im Inneren passiert
Korrosion und Oxidation greifen Kupfer mit der Zeit an, zerstören die Verbindung und verschlechtern Ihren Klang. Diese Reaktion dringt sogar in das Kabelinnere ein und verändert dessen elektrische Eigenschaften. Schrumpfschlauch allein reicht nicht aus – er verdeckt das Problem, dichtet es aber nicht ab. Dieser langsame Verfall ist der stille Killer Ihrer Kabel.
What’s Happening Inside Your Cable Over Time.
Other cables let corrosion in — we designed ours to seal it out. Most cables fail due to corrosion — causing crackling, signal loss, and eventually total failure. Our lifetime seal protects your cable from the inside out, preventing corrosion for life. Voltage-branded heat shrink is then applied over the top for added structural integrity.

Was die Profis sagen
Ich hatte es satt, ständig Kabel zu zerreißen und sie durch Drauftreten abzunutzen. Mit meinen Spiralkabeln von Voltage passiert mir das nie. Und dass sie echt cool aussehen, schadet auch nicht. Die besten Kabel, die ich je hatte, ganz klar.
„Ich nutze so viel drahtloses Internet, dass ich nie wirklich über Kabel nachgedacht habe … bis ich ein Voltage Cable bekam … jetzt greife ich jedes Mal zuerst danach.“
„Ich habe mit meinem ersten blauen Spannungskabel über 100 Stunden gespielt … jetzt benutze ich auch das cremefarbene. Es klingt jedes Mal großartig und ich liebe den Vintage-Vibe. Diese beiden sind meine absoluten Lieblingskabel.“
