HOW IT WORKS
Quality Control / Quality Assurance System
Our cables undergo strict Routine and Type Testing to ensure they deliver reliable performance, meet stringent international standards, and maintain the highest levels of reliability, safety and quality.
Because we know that quality is not merely an option — it is an imperative.
STEP 01
Visual Inspection
Each cable undergoes a thorough visual inspection to verify overall build quality and compliance with design specifications.
This includes checking conductor condition (free from oxidation or defects), stranding, insulation and sheath integrity, surface finish, cable construction, sheath colour, core identification, product markings or embossing, and cable length.
Any physical defects such as cuts, deformities, or inconsistencies are identified before electrical testing proceeds.
STEP 02
Conductor Resistance
The conductor resistance test verifies that the electrical resistance of the cable conductor complies with IEC 60228 / BS EN 60228 standards.
Using precision instruments, resistance is measured per unit length and corrected to a reference temperature of 20 °C to confirm that the conductor material, cross-sectional area, and stranding provide the required electrical conductivity for efficient current flow.
STEP 03
Voltage Test
A high-voltage withstand test is performed to confirm the integrity of the insulation system.
For single- and multi-core power cables, testing is conducted in accordance with IEC 60502-2, where a power frequency test voltage of 3.5 Uo is applied for 5 minutes between each conductor and the metallic layer.
The voltage is gradually increased to the specified level to ensure the insulation system can withstand electrical stress without breakdown.
STEP 04
Partial Discharge Test
For medium- and high-voltage cables, partial discharge testing is conducted to detect microscopic insulation defects that could lead to long-term failure.
The test is carried out in accordance with IEC 60502-2 and IEC 60885-3, with a sensitivity of 10 pC or better.
The voltage is raised gradually to 2 Uo, held for 10 seconds, and then reduced to 1.73 Uo, with no detectable discharge exceeding the specified sensitivity.
QUICK ANSWERS
Electrical Cables FAQ’s and Answers
Do you make custom made cables?
Absolutely. With your knowledge and our know-how, we design and build custom cables to meet exact project requirements. Whether that’s a simple modification to an existing product or a fully tailored solution, CCI offers a range of options for customised cables engineered to perform reliably in harsh and demanding environments.
What is the difference between Low Smoke Halogen Free (LSZH) and PVC cables?
LSZH cables emit minimal smoke and no toxic halogen gases when exposed to fire, making them ideal for enclosed or high-occupancy environments like buildings, tunnels, and transport systems. PVC cables are cost-effective and widely used but produce more smoke and corrosive gases in fire conditions.
What is the difference between armoured and unarmoured cables?
Armoured cables include a protective layer (usually steel wire armour) for mechanical protection, making them suitable for underground or harsh environments. Unarmoured cables are typically used in protected installations like conduits or cable trays.
What is the difference between copper and aluminium conductors?
Copper offers higher conductivity and durability, making it ideal for most commercial and industrial applications. Aluminium is lighter and more cost-effective for larger installations but requires proper termination techniques.
What standards do your cables comply with?
Our cables are manufactured to meet relevant Philippines, Australian and International standards. We can provide compliance documentation and certifications upon request.
