FAQ
1. What is a PVC Insulated Control Cable?
A PVC insulated control cable is a type of electrical cable with copper conductors and polyvinyl chloride (PVC) insulation. It is designed for signal and power transmission in industrial and automation control systems.
2. Where are PVC insulated control cables used?
They are commonly used in industrial machinery, automation systems, electrical panels, and building wiring for control circuits. They are suitable for fixed installations in dry or moderately humid environments.
3. What are the typical voltage and temperature ratings?
Most PVC insulated control cables have a rated voltage of 450/750V and a maximum operating temperature of 70°C. Specific ratings depend on the cable model.
4. What are the main construction features?
These cables usually have multiple copper conductor cores (bare or tinned), PVC insulation, and a PVC sheath. Some models may include shielding for EMI protection or armoring for mechanical protection.
5. How to select the right PVC insulated control cable?
Selection depends on the required voltage, current capacity, environmental conditions (humidity, mechanical stress, chemical exposure), and whether shielding or armoring is necessary. Choose the model that meets both electrical and mechanical requirements.
6.Can we get some samples? Any charges?
Yes, samples are available for testing. Standard samples are free of charge, while freight costs are borne by the buyer.Customers may also send samples for us to use as a reference for production.
