Purity test (for copper)
Confirms the metallurgical purity of our 99.99% copper conductors before use.
Annealing test (for copper)
Verifies proper elongation and flexibility so conductors resist snapping under stress.
Tensile test (for aluminium)
Checks the strength of aluminium conductors under pulling force before installation.
High voltage test (SE-3, SE-4)
Applies elevated voltage to confirm insulation can safely withstand high-voltage conditions.
Wrapping test (for aluminium)
Confirms conductors can be wrapped and formed without cracking or structural failure.
Conductor resistance test
Ensures maximum electrical conductivity with minimal energy loss across every cable.
Insulation thickness test
Measures insulation thickness precisely to guarantee consistent protection and safety.
Oil and tear resistance test
Confirms cable sheathing withstands oil exposure and resists tearing in harsh environments.
Overall diameter measurement
Verifies each cable meets exact dimensional specifications for safe, proper installation.
Tensile strength and elongation
Tests how much stretching and force cables can endure before any structural failure.
Ageing in air oven
Simulates long-term heat exposure to confirm cables perform reliably over many years.
Insulation resistance test
Confirms insulation properly blocks current leakage, keeping installations safe.
Built for Decades of Power
Cables and wires aren't something you replace every few years — once installed, they become the backbone of your entire electrical system. That's why every product we manufacture passes through this rigorous testing process, backed by ISO 9001:2015 certification and a legally registered trademark, so you can trust that what powers your home, office, or industry today will keep performing for decades to come.
