GET TO KNOW US

A sheath fault is a break down of the outer sheath. We offer a complete test, location, excavation, repair & retest service.

What is Sheath Fault?

A Sheath Fault may of occurred during installation, backfilling/reinstatement, poor extrusion of low quality cable or in the unfortunate event of excavation too close to an existing service.

Whatever the cause of the sheath fault… If it is not rectified with an immediate repair it will seldom lead to the failure of that cable.

If the sheath is damaged to such an extent that the screen beneath it is driver through the semi conductive layer and into the primary insulation this would distort the homogenous field distribution and partial discharge would develop.

Depending on the severity this partial discharge will eventually lead to the catastrophic breakdown of the cable in question.

Testing Equipment

SFS use the industry leading SebaKMT HVB10 which is a highly accurate high voltage bridge designed to locate cable and sheath faults, perform sheath testing and pinpoint sheath faults to minimise time and cost.

Although its especially suited to long HV cables it can be used on a wide variety.

Not only do we use this test kit with great confidence, we also offer a rental service to other competent engineers.

If this option suits you better just contact us.
