Copper PVC Flame Retardant Control Cable is a 450/750V control cable using high-purity oxygen-free copper conductors, mica tape and flame-retardant PVC insulation and sheath. Class 1 solid, Class 2 stranded and Class 5 flexible conductor constructions are available for different wiring conditions. The cable is intended for control, monitoring and auxiliary circuits in industrial facilities, buildings and other low-voltage electrical systems where flame-retardant and fire-resistant performance is required.

The cable construction can also include optional copper wire braiding or copper tape shielding, with core quantities from 2 to 61 cores. Selection can therefore be based on conductor type, cross-section, core quantity, shielding requirements, installation method and the applicable fire-performance requirements of the project.

Construction and Performance

Conductor Options for Different Wiring Conditions

The cable is available with solid, stranded or flexible copper conductors. Solid and stranded constructions can be used where the cable route is relatively fixed, while flexible conductors are more convenient for cabinet wiring, equipment connections and installations requiring easier cable handling. The appropriate conductor construction should be selected according to the installation method and mechanical requirements.

Mica Tape and PVC Insulation

Mica tape forms the fire-resistant layer around the conductor, while PVC provides the main electrical insulation. The outer sheath is also made from flame-retardant PVC. This combination gives the cable both a defined fire-resistant construction and flame-retardant characteristics for the applicable cable configuration.

Optional Shielding

For circuits where electromagnetic interference needs to be considered, copper wire braiding or copper tape wrapping can be specified as the shielding layer. The listed shielding coverage rate is ≥80%. Shielded construction should be selected according to the signal type, surrounding electrical equipment and installation environment.

Where the Cable Addresses Practical Wiring Requirements

Copper PVC Flame Retardant Control Cable can be configured for both fixed and more flexible control-wiring conditions. This reduces the need to select completely different conductor constructions when a project contains control cabinets, equipment connections and fixed cable routes within the same electrical system.

For circuits carrying control and monitoring signals, conductor resistance is an important specification rather than simply a material description. The technical table provides the insulation resistance, withstand-voltage and conductor-resistance requirements that can be used for technical confirmation before ordering.

Where fire protection is part of the electrical design, the cable's flame-retardant and fire-resistant characteristics should be evaluated together with cable routing, support methods and the requirements of the complete fire-protection system. Cable performance should not be considered independently from the installation method.

Application Scenarios

1. Fire-Protection Systems: Fire-protection control cabinets, alarm-related circuits, smoke-exhaust equipment and fire-water pump control systems.

2. Power Facilities: Electrical control cabinets, generator-set auxiliary circuits and control or signal wiring in power distribution rooms.

3. Industrial Automation: Control systems for production lines, machinery and process equipment where flame-retardant cable construction is required.

4. Building Electrical Systems: Elevator control systems, central air-conditioning equipment, basement machine rooms and other building automation applications.

5. General Industrial Equipment: Wastewater-treatment equipment, drying lines, machine tools and other auxiliary control circuits.

Quality and Technical Verification

For technical procurement, the main verification points include conductor construction, conductor cross-section, PVC insulation thickness, insulation resistance, withstand voltage, conductor resistance, shielding configuration and the specified fire-performance requirements. These parameters provide a more practical basis for product acceptance than general descriptions of cable quality.

Qiancheng can provide the applicable product specifications and technical documentation according to the ordered cable configuration. For engineering and export projects, requirements for test reports, certificates, inspection records, packaging and cable length should be confirmed before production.

Specification Selection Guide

Conductor Cross-Section

The available conductor cross-section is 0.5mm² to 10mm². Selection should be based on the circuit function, electrical load, allowable conductor resistance and applicable installation requirements.

Core Quantity

The standard configuration covers 2 to 61 cores. Core quantity should be determined from the number of control, monitoring and auxiliary circuits required by the equipment or project.

Shielding Requirements

Where signal interference is a concern, copper wire braiding or copper tape shielding can be considered. The required shielding method should be confirmed according to the electrical environment and control-system requirements.

Fire Performance

The technical table specifies a fire exposure condition of no less than 830℃ for 90 minutes and flame-retardant requirements under GB/T 19666. The required test condition and documentation should be confirmed against the actual project specification before order placement.

FAQ

1. What standards are specified for this cable?

The technical data references GB/T 9330 for DC conductor resistance and GB/T 19666 for the listed flame-retardant requirements. Any additional certification or test documentation required for an export project should be confirmed according to the ordered cable configuration.

2. What conductor constructions are available?

The cable can be configured with solid rigid conductors or multi-strand flexible conductors. The suitable construction depends on whether the installation is fixed, routed through a control cabinet or requires greater flexibility during installation.

3. What cross-sections and core quantities are available?

The listed conductor cross-sections range from 0.5mm² to 10mm², with core quantities from 2 to 61 cores. The final combination should be confirmed according to the circuit design and cable configuration.

4. Can the cable be shielded?

Yes. Copper wire braiding or copper tape wrapping can be specified as an optional shielding layer, with a listed shielding coverage rate of ≥80%.

5. Where is this Copper PVC Flame Retardant Control Cable commonly used?

It is used for control, monitoring and auxiliary circuits in fire-protection systems, power facilities, industrial automation equipment, building electrical systems and other industrial applications where the specified flame-retardant and fire-resistant characteristics are required.

6. What information is needed for a quotation?

Provide the required model, conductor type, cross-section, core quantity, shielding requirement, cable length, installation environment and applicable fire-performance requirements. Any required inspection reports, certificates or export documentation should also be specified in advance.
