TRACKING

• MOISTURE

- Humidity- Fog- Condensation- Mist- Snow- Rain

• CONTAMINATION

- Dust- Chemicals- Salt- Other Airborne Particles

• VOLTAGE- Surface Stress (V/mil)

- Silicone Rubber

- Inorganic Fillers in EVA (Heat Shrink)

- Inorganic Fillers in Rubber

2. Rain Shed (Insulator Skirts)

1. Increase Distance from HV to Ground

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)

CABLE SPLICING/JOINTING

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


64

Common Steps for POWER CABLE SPLICING

• Properly Prepare Surface• Join Conductors with a Connector

• ReInsulate Main Insulation•Re-Estbalish Shield system Continuity

• Re Jacketing



FIELD PROBLEM

MV Cable preparation tools

Cable Jacket Cutter

Peel-able SemiconductivePeeler

Bonded Semiconductive Peeler

Safe removal of insulation screen

Good quality stripping tools.
