The SheathEx™ Process
The most recent innovation in continuous extrusion is the BWE patented SheathEx process.
A Metallic Sheath is utilised in cables to prevent the ingress of moisture without diminishing the flexibility of the cable. Water penetration is detrimental to the integrity of insulation. The combination of moisture and high electrical stresses leads to the initiation of water tree growth, resulting in the premature failure of the cable.
