Technical Specifications

Note: The final conductor size, conductor class, insulation and sheath materials, screen arrangement, armour structure, flame retardant classification, and applicable standard should be specified in the approved technical datasheet.

Cable Construction

1. Copper Conductor

The cable uses copper conductors to provide reliable electrical conductivity for control circuits. Conductor cross-sectional area and construction can be selected according to the required current, voltage drop, installation conditions, and project specification.

2. Insulation

The insulation separates individual conductors electrically and provides the required dielectric performance. The insulation material and thickness are selected according to the rated voltage and applicable product standard.

3. Core Identification

The four cores can be identified by numbered cores or agreed colour coding, depending on the project specification and applicable standard. This helps simplify installation, circuit identification, and maintenance.

4. Copper Tape Screen

The copper tape screen provides a conductive screening layer around the cable cores or core assembly, depending on the selected construction. It helps control electromagnetic interference when used with an appropriate grounding arrangement.

The screen design should be selected according to the application, grounding method, and required electrical performance.

5. Inner Sheath or Bedding

An inner sheath or bedding layer may be incorporated beneath the steel tape armour where required by the selected cable construction. Its material and thickness depend on the applicable standard and mechanical design.

6. Steel Tape Armour

Steel tape armour provides additional mechanical protection for suitable fixed-installation applications. It can help protect the cable against external mechanical damage during installation and service.

The suitability of steel tape armour depends on the installation environment. Where tensile loading, repeated movement, or special corrosion resistance is required, the armour and cable design should be reviewed accordingly.

7. Flame Retardant Outer Sheath

The outer sheath protects the cable assembly against external environmental influences. Flame retardant materials can be selected to meet the specified flame propagation requirements.

Flame retardant performance is test-specific. The required standard, test method, and classification should be agreed before production.

Typical Applications

Industrial Automation and Control Systems

Used for control wiring between industrial equipment, control panels, and electrical systems where a screened and armoured cable construction is required.

Manufacturing Plants and Industrial Facilities

Suitable for selected fixed-installation control circuits in manufacturing facilities, workshops, and industrial plants, subject to the cable design and installation conditions.

Electrical Equipment Connections

Can be specified for control connections between electrical equipment and associated control systems where four cores, copper tape screening, and steel tape armour meet the project requirements.

Infrastructure and Engineering Projects

Suitable for consideration in industrial infrastructure and engineering projects requiring flame retardant control cables with screening and mechanical protection.

Equipment and Machinery Control

Can be used for fixed control wiring in machinery and equipment installations where the specified cable construction and voltage rating are appropriate.

Important: This cable should not automatically be treated as a fire-resistant or circuit-integrity cable. Flame retardant performance limits flame propagation under specified test conditions; it does not necessarily guarantee continued circuit operation during a fire.

Flame Retardant Control Cable vs. Standard Control Cable

The appropriate cable should be selected based on the required fire performance, electrical characteristics, screening requirements, mechanical protection, and installation conditions.

Frequently Asked Questions

1.What is a flame retardant control cable?

A flame retardant control cable is designed to meet specified flame propagation requirements. It is used in control circuits where limiting the spread of fire along a cable route is an important consideration.

2.What is the function of the copper tape screen?

The copper tape screen provides a conductive screening layer that can help reduce electromagnetic interference when correctly designed and grounded. Its effectiveness depends on the screen construction, grounding arrangement, and installation environment.

3.What is the advantage of steel tape armour?

Steel tape armour provides additional mechanical protection for suitable fixed installations. It helps protect the cable from certain forms of external mechanical damage, but it is not a substitute for proper cable routing and installation protection.

4.Is flame retardant cable the same as fire-resistant cable?

No. Flame retardant cable is designed to limit flame propagation under specified test conditions. Fire-resistant cable is designed to maintain circuit integrity for a specified period under defined fire test conditions. The required performance should be identified clearly in the project specification.

5. Can this cable be manufactured to a specific standard?

The applicable standard depends on the required cable construction, voltage rating, fire performance, and destination market. Zhongdong Cable can review the requested standard and technical specification before confirming the proposed design.
