XLPE Copper Control Cable

Product Models: KYJV, KYJVP, KYJV22, KYJY, etc.

XLPE Copper Control Cable is used for low-voltage control, instrumentation and signal circuits where the insulation system needs to accommodate elevated operating temperatures. The standard construction combines high-purity oxygen-free copper conductors with XLPE insulation and a PVC outer sheath, with unarmored, shielded and steel-tape armored configurations available for different installation conditions.

The supplied technical data specifies a rated voltage of 450/750V, a maximum long-term operating temperature of 90 °C and standard conductor cross-sections from 0.75 to 6 mm². Depending on the circuit and laying method, the cable can be supplied with solid or flexible conductors, multiple core configurations, shielding, armoring or WDZ low-smoke zero-halogen construction.

Product Specification, Dimensions and Technical Parameter Table

Construction and Electrical Characteristics

1. XLPE Insulation

Cross-linked polyethylene forms the primary insulation layer. The supplied specification gives a maximum long-term operating temperature of 90 °C and a short-term overload tolerance of 130 °C. This temperature range is one of the main reasons to consider XLPE insulation when a control installation may operate above the typical conditions of general-purpose PVC-insulated wiring.

2. Copper Conductor Options

The conductor is specified as 99.99% high-purity oxygen-free copper. KYJV uses a Class 1 solid conductor, while KYJVR is listed with a Class 5 flexible conductor. The conductor construction can therefore be matched to fixed wiring or installations where additional flexibility is required.

3. PVC Sheath and Functional Variants

The standard outer sheath is PVC, with a WDZ low-smoke zero-halogen version available as an upgraded option. Shielded KYJVP adds copper-braided shielding, while KYJV22 uses steel-tape armor for applications requiring additional mechanical protection. These variants allow the cable construction to be matched to the surrounding installation rather than using one configuration for every project.

Selecting the Right Configuration

Core quantity should correspond to the number of control, instrumentation or protection circuits served by the cable. The standard range covers 2 to 61 cores, while conductor cross-sections range from 0.75 to 6 mm². The required conductor size should be determined from the circuit load, permissible voltage drop and installation conditions rather than selected solely by the number of cores.

Installation conditions determine whether additional protection is needed. Unarmored KYJV or KYJVR is intended for cable trays, indoor conduits and fixed cable-trench wiring. KYJVP can be considered where electromagnetic interference is a concern, while KYJV22 is intended for specified installations requiring steel-tape armor and mechanical protection. The supplied minimum bending-radius values should also be considered during routing.

Typical Applications

1. Energy and Electrical Equipment

The cable can be used for low-voltage control and signal wiring associated with PV equipment, energy-storage systems, inverters, electrical cabinets and related equipment. XLPE insulation provides the specified 90 °C long-term operating temperature range for installations where ambient or equipment temperatures require this level of insulation performance.

2. Industrial Automation

Control cabinets for machine tools, pumps, fans, PLC systems and process equipment may require multi-core control wiring with different conductor and installation configurations. Flexible conductor versions can simplify routing around equipment terminals and cabinets, while shielded versions are available for circuits where electromagnetic interference needs to be addressed.

3. Municipal and Building Infrastructure

The cable range can be used in underground utility tunnels, cable trenches, building electrical systems and other fixed low-voltage control installations. Where cables are exposed to additional mechanical loading or require direct-burial construction, the armored KYJV22 configuration provides a different installation option.

4. Power-System Control and Protection

Low-voltage secondary circuits in substations, power plants, distribution rooms and electrical equipment can use multi-core control cables for signal acquisition, interlocking and equipment control. The final model should be matched to the circuit function, conductor size, shielding requirement and installation method.

5. Export Equipment and Engineering Projects

For export-oriented electrical equipment and engineering projects, the cable specification should be confirmed against the applicable project requirements before production. Documentation, delivery length, reel type and any required inspection records can be specified together with the cable model and construction.

Technical Checks Before Ordering

For a project quotation, the basic information normally includes cable model, rated voltage, conductor class, cross-section, core quantity and required length. If the cable will be routed near equipment that generates electromagnetic interference, the shielding requirement should be stated separately. Direct burial or exposed installation should also be identified so that the need for armor can be evaluated.

For export orders, packaging and documentation should be confirmed at the quotation stage. The supplied specification lists plastic reels and fumigated wooden reels, together with customized delivery lengths. Special requirements such as WDZ low-smoke zero-halogen construction or cold-resistant versions should also be specified before production.

FAQ

1. What standards are specified for this cable?

The supplied product data lists GB/T 9330 as the national standard. If an overseas project requires additional standards, certificates or inspection documents, those requirements should be confirmed according to the destination market and project specification.

2. What conductor sizes and core quantities are available?

Standard conductor cross-sections are 0.75, 1.0, 1.5, 2.5, 4 and 6 mm². Standard core configurations range from 2 to 61 cores, including multiple intermediate core counts. Special core quantities can be produced according to project requirements.

3. What is the operating temperature of the XLPE insulation?

The supplied technical data specifies a maximum long-term operating temperature of 90 °C and a short-term overload tolerance of 130 °C. The standard minimum laying temperature is ≥0 °C, while a cold-resistant version is listed for direct installation at -30 °C.

4. When is a shielded or armored version required?

Shielded KYJVP can be considered when electromagnetic interference needs to be controlled in the signal or control circuit. Armored KYJV22 is intended for laying conditions requiring additional mechanical protection, including specified direct underground burial. The minimum bending-radius requirements are different for unarmored, shielded and armored constructions.

5. What electrical tests are specified before delivery?

The supplied specification lists an insulation resistance of ≥1000 MΩ·km at 20 °C and a finished-product withstand-voltage test of 3000V/5min with no breakdown. The table also specifies full inspection before delivery. Any project-specific inspection or third-party testing requirements should be confirmed before production.

6. Can the delivery length and cable construction be customized?

Yes. The supplied data lists customized delivery lengths with a stated length tolerance of ±0.5%. Special core quantities, flexible conductor construction, shielding, armoring, WDZ low-smoke zero-halogen construction and cold-resistant versions can be specified according to the project requirements.
