Reasearch and Development

Derul emhasize on product quality assurance and innovation, so we can keep improving our competity in the market.


The fast changing global market pushes us to adapt quickly to the appearing demands. Our team focus on smart and effective solution to these new demands. 


We are keeping exploring the technical possibilities in aspects of material science guranteed by testing methods. Cable design is also an important area to the superior performance.


The integration of cutting-edge material and advanced design, along with reliable manufacturing process control, are our key to meet our customers' needs.



We spent a lot on our R&D each year. Lab test is one of the key to ensuring the stable quality and new product innovation.

Electric/ Electronic Test

Derul have close partnership with leading companies in telecommunications, broadcasting, data transmission, automation and offshore & railway segments. We measure the cable's resistance, capacitance, impedance, return loss, attenuation, cross-talk and skew time. Those parameters are totally considered during the design of cable.


The CPMS transmission parameters are adopted to the test to examine the performance of LAN cable, coaxial cable and twisted cable. Our testing system was validated by major telephone companies.


Electric/ Electronic Test

Resistance Test

Megohmmeter is adopted to check 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 adopting megohmmeter for cable with cross-section larger than 16 mm².

Physical & Chemical Test

Physical and chemical properties of all cable component must be tested to ensure that all theproperties remain still for the entire life-cycle.

Hot Particle Resistance Test

Carried out by applying a hot wire against the cable jacket with a certain pressure during limited time, and verifying the cable integrity.

Abrasion Resistance Test

Applied to compare the cable's consumption performance under different roughness degrees.

Extreme Temperature Resistance Test

To test the performance of cable under extremely low temperature till -70°C.

Mechanical/ Dynamic Test

Adopting automation equipment to test the cable performance under dynamic working conditions.

Cable Chain Test

Flexible cable chain with high dynamic performance, small bending radius, high speed and acceleration are outstanding for applications in industrial automation. At present, the capable test is for those cables with radius from 15 mm to 250 mm. The test for drag chain is driven by brushless servo motors.

Robot work Simulation Test

Derul apply special test to simulate robot movement, with test with millions of cycles for the stable performance of the cable in the application of automation.

Torsion Simulating Test

Special devices are adopted to test the parameters including: angle rotation, twisting length, bending radius, speed and acceleration.

Fire Resistance Test

Comply with CEl EN 50200 and CEl EIC 60331.

Fire & Flame Behavior Test

Comply with the standard for fire & flame resistance, adopting tests referring special standards.
