What Does Proper Termination Look Like?
To ensure reliable and safe cable terminations, the following best practices are essential:
- Follow Guidelines: Adhere to manufacturer instructions for proper installation.
- Use Certified Kits: Use terminators and splicing kits approved by agencies like Aramco and SEC.
- Perform Maintenance: Regularly inspect and maintain to prevent failures.
- Protect Against Environment: Use UV-resistant and waterproof materials.
- Document Processes: Keep records of installation and testing procedures.
- Test Thoroughly: Conduct insulation resistance and continuity tests.
- Be Prepared: Keep spare kits and tools for emergencies.
- Ensure Connection Tightness: Avoid mechanical stress or loose joints.
Risks of Poor Termination Practices
Poor cable termination leads to insulation damage, causing cable failures and frequent faults. It results in overheating, damaging equipment and increasing downtime. Safety risks like arc flashes and fires endanger personnel and infrastructure. Proper practices are essential for reliability and safety.

Your Go-To Experts for Cable Termination
At Petozoe, we specialize in providing top-notch cable termination services for both low-voltage (LV) and medium-voltage (MV) cables. Our services are designed to ensure reliable and safe operations, adhering strictly to international standards such as IEC and Saudi Aramco specifications.
Standards Compliance
- Low Voltage (LV) Cables: Our termination services comply with IEC 60502-1 and Saudi Aramco SAES-P-104, covering power cables with extruded insulation for voltages from 0.6/1 kV.
- Medium Voltage (MV) Cables: We adhere to IEC 60502-2 and Saudi Aramco SAES-P-104, specifying power cables with extruded insulation for voltages from 2 kV up to 34.5 kV. Additionally, IEC 60332-3 ensures flame-retardant properties through fire performance tests for bundled cables.
Types of Cable Termination Services We Offer
Type -Specific Terminations
- Heat Shrinkable Terminations: Reliable heat shrinkable terminations suitable for both indoor and outdoor applications, using heat to create a tight seal and controlled electric field distribution.
- Cold Shrink Terminations: Ideal for high-humidity areas or flame-restricted zones. These involve pre-shrunk components that expand upon cable insertion, eliminating the need for heat.
- GIS Terminations: Specialized for connections to gas-insulated switchgear (GIS), meeting specific GIS system requirements.
- Screen Separable Terminations (T-Type): Designed for applications where the screen needs to be separated, ensuring precise and reliable connections.
Location-Specific Terminations
- Outdoor Terminations: UV-resistant materials ensure durability in open-air environments.
- Indoor Terminations: Space-efficient and easy to install, suitable for indoor environments.
- Underground Terminations: Engineered to withstand moisture and soil chemicals in underground installations.
- Substation Terminations: Meet the high reliability and safety standards required in critical infrastructure.
General Procedures for Cable Termination
- Cable Preparation: Inspect for compliance, strip jackets carefully, and clean conductor ends with approved solvents.
- Stress Relief: Apply semi-conductive or stress control materials to manage electric field distribution.
- Installation: Use heat or cold shrink tubing, and securely position and crimp lugs/connectors with hydraulic crimpers.
- Testing and Verification: Perform continuity and insulation resistance tests, and for MV cables, conduct HiPot testing.
- Final Steps: Inspect the termination visually, ensure proper sealing, and document the process.
