ShowMeCables Plenum rated VGA cables are specialty
cables that conform to Article 800 of the NEC. They have passed stringent burn tests
and can be run in drop ceilings and non-ducted HVAC air returns. This requirement for specialty
cables is common in commercial buildings or educational buildings. Consult your local
electrical code to know if you need plenum cables. Besides the specialty jacketing, these cables
are constructed of many coax cables. They have a tinned copper braid providing 97% coverage
for the shield.
