TECNIKABEL works jointly with customers who are leaders in the telecommunications, broadcasting, data transmission, automation, offshore and railway segments. Specific products require measuring particular transmission features, such as: resistance, electric capacitance, impedance, return loss, attenuation, cross-talk, skew time, etc. These measures provide feedback for design and are useful for project validation and cable prototyping.
The CPMS transmission parameter test bench has three different sections for measuring the transmission features of:
- LAN cables to a frequency of 600 Mhz
- coaxial cables
- paired cables.
The bench consists of:
- a network analyser (up to 3 Ghx)
- an LCR meter
- hardware and software for data acquisition and processing.
This test bench was validated by major telephone companies for approval testing (ADSL, coaxial, paired, etc.).
The transmission test system is completed with a set of HP 4194 A and HP 8753 A network analysers spanning from a frequency range of a few Hz to 3 Giga Hertz.

Dielectric resistance test
A General Radio 1836 megohmmeter and a SATURN ISO megohmmeter are used to test the quality of insulation materials.
Dielectric rigidity test
These tests are carried out on small-sized specimens of to 5 kV in the laboratory using an alternating voltage generator. A high voltage cabin is used for larger specimens (up to 20 kV).
Current stability tests
These tests are carried out using a direct voltage generator up to 10 KV.
Cable operating voltage tests
These tests are carried out in two high-voltage cabins with capacity of up to 20 kV and 30 kV respectively.
High-resolution electric resistance tests
These tests are carried out using a nanohmmeter for cables with cross-section area larger than 16 mm².
