R&D
The research and development of Derul Cable is essential to our quality assurance and product innovation, thus it is one of the top priorities of the company.
On one hand, the fast changing market requires us to adapt quickly to the various demands of the market. On the other hand, high-level workers and manufacturing equipment, advanced technology, reliable material and strict lab tests enhance ensure the stable high quality of the product. In one word, we provide technology support and innovative & quality product to satisfy our customers' updating demands.
We spent much resources on R&D every year. In the aspect of lab tests, we applied various kinds of tests to ensure the stable quality:
Electric/ Electronic Test
Derul set close partnership with customers who are leading in telecommunications, broadcasting, data transmission, automation and offshore & railway segments. Those products offered require specific transmission features as: resistance, capacitance, impedance, return loss, attenuation, cross-talk, skew time, etc... These parameters are considered during the design of the cables.
The CPMS transmission parameters are adapted to the test to test the performance of LAN cables up to 600 Mhz frequency, coaxial cables and twisted cables, and the testing system was validated by major telephone companies.
Resistance Test
Megohmmeter adapted to verify the quality of insulation materials.
Rigidity Test
The test is carried out by AC generator from 2-25 kV.
Current Stability Test
Carried out by DC generator up to 12 kV
Operating Voltage Test
Carried out by adapting two high-voltage equipment from 20-30 kV.
High-resolution Electric Resistance Test
Carried out by adapting megohmmeter for cables with cross-section larger than 16 mm².
Physical & Chemical Test
Physical and chemical properties of all cable components must be tested to guarantee that all theproperties remain still for the entire life-cycle.
Hot Particle Resistance Tests
Carried out by applying an hot wire against the cable jacket with a certain pressure for some time, and, and verifying the cable integrity.
Abrasion Resistance Test
Applied to compare a certain cable’s consumption performance under different roughness degrees.
Extreme Temperature Resistance Test
To test the performance of cables under extremely low temperature till -70°C.
Mechanical/ Dynamic Test
Adapting several automation equipment to test the cable performance under dynamic conditions.
Cable Chain Test
Cable chains with high dynamic performance, smaller bending radius, high speed and acceleration are outstanding for applications in industrial automation and machinery. At present, the capable test is for those with radius from 15 mm to 250 mm. The reliability test for drag chains is driven by brushless servo motors.
Robot Simulation Test
Derul cooperate with leading robot factories in developing mechanical simulators for simulating robot movement, to have tests with millions of cycles to ensure the stable performance of the cable.
Torsion Simulating Test
Derul has special devices designed to test these parameters: angle rotation, twisting length, bending radius, speed and acceleration, and combination of different bending and twisting movements.
Fire Resistance Test
According to CEl EN 50200 and CEl EIC 60331.
Fire & Flame Behavior Test
Under the strict standard for fire & flame resistance, adapting 3 test referring standards including:
- UL standards (Cable Flame, VW1, Horizontal Flame Test)
- CSA (FT1. FT2)
- CEI (20-35/1, 20-35/2, IEC 60332-1, IEC 60332-2).
