Cable Testing at TACS Laboratories

At TACS Laboratories we do testing according to SANS, IEC and BS standards.

 

We do testing on Power Cables such as:

• Cabtyre
• House Wire
• Twin + Earth
• Suffix
• LV PVC Distribution cables
• LV XLPE Distribution cables
• Overhead Aerial Bundle Conductors
• LV Trailing Cables
• Physical testing of MV and HV XLPE and PILC Cables
• etc.

 

Overhead Conductors such as:

• ACSR
• Copper Conductors
• Aluminium Conductors (Aluminum Conductors)

 

Type of Tests/Properties Measured, Range of Measurement includes the following:

 

Construction requirements and Material Testing

• Dimensions
• Tensile Strength and Elongation at Break on materials before and after Ageing in air Oven
• Oil resistance testing
• Pressure Test on Insulations and Sheath at High Temperature (indentation)
• Environmental Stress Cracking, Cable Mechanical Flexing Test, Heat Shock Test on Insulation & Sheath
• Halogen Emission
• Bending at Low Temperature on Insulation and Sheath
• Limiting Oxygen Index
• Loss of Mass (Sheath and Insulation)
• Elongation at Low Temperature
• Impact at Low Temperature
• Solderability of Untinned Conductors
• Degree of Cross-linking (Hot Set Test)

 

We also perform Fire Propagation Testing and Smoke Emission test

 

Armouring/Overhead Conductors

• Mass of Zinc Coating
• Tensile Strength
• Uniformity of Zinc Coating
• Adhesion of Zinc Coating
• Conductor Breaking Force

 

Electrical Testing

• Electrical Conductor Resistance
• Insulation Resistance
• Voltage Withstand Test
• Braided Screen Resistance
• Dielectric Breakdown
• Dielectric Strength test
