PVC Jacket VS Rubber EPDM Insulation [2011-02-16]
Assume you need 4 wires to power your connection. Running each wire individually would be the old fashioned way but now manufacturers surround all 4 wires with a PVC or Rubber jacket for protection and ease of installation.PVC JacketA PVC jacket is cheaper than rubber because it doesn’t offer the same amount of environmental or impact resistance that the inner wires may need. Romex, for instance, is an indoor cable but having an electric cable with all the wires is much easier than running them individually. So is there a point to having an expensive rubber jacket on it?
