Silicone Rubber for TerminationINSULATOR MATERIAL
1. Silicone is Hydrophobic
2. Silicone Can Recover Its Hydrophobicity
3. Silicone is Inherently UV-Stable
4. Silicone is Mostly Inorganic --(No Conducting Carbon Path)
5. Silicone Has a Smooth Surface

“Why Splice a Shielded Power Cable?”
• Supplied length is not long enough (reel end)• Length is limited due to pulling distance and bends
• Cable failure• Cable damaged after installation (e.g. dig-in)• Tap into an existing cable (Tee or wye splice)

A Splice can be defined as two or more conductorsjoined with a suitable connector
re-insulatedre-shielded and
re-jacketed with compatible materials

FUNCTION OF MEDIUM VOLTAGE SPLICES• Control Electrical Stress in Connector Area
• Insulate Between Voltage and Ground• Maintain Metallic Shield Continuity• Provide Protection from Impact and Moisture• Provide Resistance to Acidic & Alkaline Soil
