11kV OUTDOOR Termination Kits

To perform an 11kV outdoor termination, you must first prepare the cable by stripping its outer jacket and insulation, then install an integrated electrical stress control device. Next, apply a termination kit (usually cold shrink for outdoor use) over the cable's conductor to provide insulation and protection. A proper termination also involves attaching a cable lug to the conductor, securing the armour continuity, and installing integrated rain sheds for electrical insulation and moisture sealing.
Steps for 11kV Outdoor Termination
Key Considerations
Steps for 11kV Outdoor Termination
- 1. Cable Preparation:
- Clean the cable and strip the outer jacket and insulation to expose the conductor, following the specific dimensions provided in the kit's instructions.
- 2. Stress Control Installation:
- Install the integrated electrical stress control device, which is part of the termination kit. This device is crucial for dissipating electrical stress at the point where the cable insulation is cut, ensuring reliable operation.
- 3. Termination Kit Installation:
- For outdoor applications, a cold shrink termination kit is typically used. These kits come pre-expanded on a plastic core.
- Pull and unwind the plastic support core counter-clockwise to shrink the termination body onto the cable.
- 4. Lug Attachment:
- Attach a suitable cable lug to the exposed conductor using a crimping tool or mechanical shearbolt lugs, following the manufacturer's recommended torque.
- 5. Moisture Sealing & Protection:
- Apply mastic tape to seal the connection, ensuring a waterproof seal.
- Secure armour continuity components if the cable has an armour.
- Install the rain sheds and re-jacketing tubes to provide insulation and protection from moisture and tracking, as specified in the kit's instructions.
Key Considerations
- Safety:
Always use correct cable jointing tools and follow the manufacturer's instructions to avoid installation faults. - Kit Type:
Cold shrink terminations are preferred for outdoor installations, especially in locations with a risk of fire, as they do not require a naked flame. - Components:
Ensure the termination kit includes essential components like the silicone rubber body, integrated stress control, re-jacketing tubes, and rain sheds. - Cable Type:
The kit must be appropriate for the cable's cross-section and voltage class, such as an 11kV XLPE cable. - Standards:
Terminations should meet relevant international standards like CENELEC HD 629.1 or IEC 60502-4.
