Cable Laying

• Purpose: The laying of cables involves the safe and efficient installation of electrical cables in the designated pathways, including underground, overhead, or within buildings.
• Benefits: Proper cable laying prevents mechanical stress, reduces the risk of damage during installation, and ensures that the cables are securely positioned for optimal performance. Correct installation also extends the lifespan of cables and minimizes the risk of future failures.
• Procedure: Our team follows industry standards and best practices when laying cables. We ensure the correct type, size, and insulation for the specific application and follow guidelines for proper bending radius, spacing, and securing of cables to prevent damage.

Cable Termination

• Purpose: Cable termination involves connecting the ends of electrical cables to equipment, switches, or other cables. Proper termination is essential for ensuring secure, stable, and reliable electrical connections. This process includes preparing, sealing, and securing cable ends to ensure safety and optimal performance.
• Benefits: Correct cable termination prevents issues like overheating, shorts, and signal loss, ensuring that your system operates reliably and safely. Well-executed terminations also help avoid costly faults, downtime, and maintenance issues.
• Types of Cable Termination:
  • Copper Cable Termination: Copper cables are widely used for their excellent conductivity. Terminating copper cables requires careful preparation and proper connectors to ensure a low-resistance connection and minimize the risk of electrical losses or failures.
  • Aluminium Cable Termination: Aluminium is a lightweight alternative to copper and is commonly used in power distribution. We use specialized techniques and connectors to ensure a secure and low-resistance termination for aluminium cables, which are prone to oxidation.
  • Armoured Cable Termination: Armoured cables are used in environments where the cable needs to be protected from physical damage. Proper termination of armoured cables involves stripping the outer layer and ensuring that the armour is correctly grounded and the cable is sealed to prevent moisture ingress.
  • Non-Armoured Cable Termination: Non-armoured cables are commonly used in less hazardous environments. For these cables, proper insulation, sealing, and connection techniques are employed to ensure a safe and reliable electrical connection.
• Procedure: Our skilled technicians use advanced tools and materials to prepare and terminate cables in accordance with manufacturer specifications and industry standards. This involves cleaning, stripping, and crimping cable ends, and applying the appropriate insulating materials and sealing compounds for both high-voltage and low-voltage cables to protect against moisture, dirt, and environmental factors.

High Voltage Cable Testing

• Purpose: Verifies the integrity and performance of high-voltage cables, including insulation and continuity.
• Benefits: High-voltage cable testing ensures that cables can safely handle the required electrical load under normal and fault conditions. It helps detect insulation breakdowns, weak connections, and hidden faults that could lead to failures.
• Procedure: We perform insulation resistance testing, high-voltage withstand testing, and continuity testing to confirm that cables meet safety standards and are free from faults that could impact system reliability.

DC Conductor Resistance Test

• Purpose: Measures the resistance of conductors in DC circuits to ensure they have low enough resistance for efficient operation.
• Benefits: High resistance can lead to energy loss, overheating, and reduced system efficiency. By measuring the DC resistance of conductors, we can identify and correct potential issues, ensuring optimal performance.
• Procedure: Using specialized equipment, we apply a DC voltage to the cable and measure the resulting current to calculate the resistance. The test ensures that the conductor’s resistance is within acceptable limits and complies with industry standards.

Sheath Integrity Test

• Purpose: Verifies the integrity of the outer sheath of the cable, ensuring it is intact and can protect the conductors from external damage.
• Benefits: An intact sheath is essential for preventing moisture ingress, physical damage, and electrical faults. This test ensures the sheath is free from damage that could lead to system failures.
• Procedure: The sheath integrity is tested by applying a low-voltage signal to the cable’s outer sheath and checking for any signs of leakage or breakage. This test helps confirm that the cable is properly sealed and capable of withstanding environmental conditions.

Loop Integrity Test

• Purpose: Assesses the continuity and quality of the looped cable circuits, ensuring that there are no breaks or weaknesses.
• Benefits: A complete and intact loop is essential for systems that rely on closed circuits for proper functioning, such as in control and signaling systems. This test helps ensure the integrity of cable loops, preventing faulty connections and ensuring reliable operation.
• Procedure: We test the cable loop by measuring resistance across the loop and checking for any breaks or variations in continuity. The test ensures that the loop is fully intact and capable of carrying the required current without interruptions.

Phase Identification Test

• Purpose: Ensures that cables are correctly connected to their respective phases to maintain the correct electrical sequence and prevent operational issues.
• Benefits: Proper phase identification prevents issues like phase imbalances, equipment damage, or system inefficiencies. It is critical for applications where proper phase sequence is essential for motors, generators, and other equipment.
• Procedure: We use phase testers to identify and verify the correct phase sequence across all conductors. The test ensures that the cables are connected to the correct phases and that the system is configured properly to avoid any operational anomalies.

Cable Fault Location

• Purpose: Detects faults such as open circuits, short circuits, or insulation failures within cables.
• Benefits: Early fault detection prevents downtime, minimizes repair costs, and helps avoid further damage to the system. Locating faults quickly is essential for maintaining system reliability.
• Procedure: Using advanced fault location equipment like time-domain reflectometers (TDR) or acoustic sensors, we pinpoint the exact location of any faults in the cable, enabling fast and accurate repairs.

Cable Insulation Resistance Testing

• Purpose: Measures the insulation resistance of the cables to ensure they can safely operate without leakage or risk of short-circuiting.
• Benefits: Strong insulation resistance is vital for preventing electrical hazards, system failures, or downtime due to damaged insulation. This test provides an early warning of insulation degradation or moisture ingress.
• Procedure: A high-voltage DC test is applied to the cable insulation, and the resistance is measured to ensure it meets the required standards for safe operation.
