Equipment calibration: Regularly calibrate key equipment such as wire drawing machines, stranding machines, extruders, and diameter gauges to ensure that the accuracy meets the requirements.
First piece confirmation: Before each batch of production, the first piece is trial-produced to confirm that the process parameters, product dimensions, electrical performance, etc. meet the standards before mass production can be carried out.

Finished Product

Inspectors conduct ex-factory inspections on cables according to relevant standards and corresponding product inspection specifications to ensure that each ex-factory product complies with the process regulations.

Instrumentation Cables—XLPE Insulated, Overall Screened ,Unarmoured PVC Sheathed Cables(CU/XLPE/OSCR/PVC)

Instrumentation cables come in twisted pairs, triads, and quads, depending on the customer’s applications; twisting reduces any electromagnetic interference by reducing the chances of electrical voltages and currents being induced in the conductor. Individual and overall screening are also applied in instrumentation cables to optimize the signal transferred and further reduce any electromagnetic interference. Screening of pairs, triads, or quads also includes a drain wire earthed to the ground, which ensures a noise-free signal transmission. Depending on the application, instrumentation cables can be insulated with PVC or XLPE; the cables can be armoured or unarmoured. The sheathing materials can be of PVC, LSZH, or PE. The cables can have additional flame retardant or flame retardant properties, and they can be manufactured with special protections such as lead sheaths, or DRYLAM or AIRBAG technology.

FAQ From Customers

What are the advantages of power cables and overhead lines?

(1) Reliable operation, because it is installed in a hidden place such as underground, it is less damaged by external forces, has less chance of failure, and the power supply is safe, and it will not cause harm to people;
(2) The maintenance workload is small and frequent inspections are not required;
(3) No need to erect towers;
(4) Help improve power factor.

Which aspects should be considered when choosing the cross section of a power cable?

(1) The long-term allowable working current of the cable;
(2) Thermal stability once short circuited;
(3) The voltage drop on the line cannot exceed the allowable working range.

What are the measures for cable fire prevention?

(1) Use flame-retardant cables;
(2) Use fireproof cable tray;
(3) Use fireproof paint;
(4) Fire partition walls and fire baffles are installed at cable tunnels, mezzanine exits, etc.;
(5) Overhead cables should avoid oil pipelines and explosion-proof doors, otherwise local pipes or heat insulation and fire prevention measures should be taken.

What should be paid attention to during the transportation and handling of cables?

(1) During transportation, loading and unloading, cables and cable reels should not be damaged. It is strictly forbidden to push the cable reels directly from the vehicle. Generally, cables should not be transported and stored flat.
