Ways To
CONTROL TRACKING
1. Increase Distance from HV to Ground
2. Rain Shed (Insulator Skirts)
3. Track Resistant Materials
- Porcelain
- Inorganic Fillers in Rubber
- Inorganic Fillers in EVA (Heat Shrink)
- Silicone Rubber
Silicone Rubber for Termination
INSULATOR 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
Examples

CABLE SPLICING/JOINTING
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)

CABLE SPLICING/JOINTING
A Splice can be defined as two or more conductors
joined with a suitable connector
re-insulated
re-shielded and
re-jacketed with compatible materials
CABLE SPLICING/JOINTING
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
CABLE SPLICING/JOINTING
Common Steps for POWER CABLE SPLICING
Properly Prepare Surface
Join Conductors with a Connector
ReInsulate Main Insulation
Re-Estbalish Shield system Continuity
