Control Cable N2XBY XLPE Insulated -CU/XLPE/PVC/STA/PVC- STA Steel Tape Armoured Cable

Control cables transmit control and measuring signals rather than heavy power. They are widely used in power stations, substations, industrial automation, fire protection, buildings, new energy and municipal projects. Various types with shielding, fire resistance, flexibility and armor are available to fit indoor, outdoor, buried and harsh industrial installation environments.

CHARACTERISTICS

Characteristics of XLPE Insulated Steel Tape Armored Control Cables

1. Basic Structure & Standard Model

Main model: KYJV22

Layer structure from inside out: Copper conductor → XLPE cross-linked polyethylene insulation → PVC inner bedding → Double steel tape armor → PVC outer sheath

Shielded derivative models: KYJVP22 (copper braided shield), KYJVP2-22 (copper tape shield)

It combines XLPE’s excellent electrical & thermal performance with steel tape armor’s outstanding horizontal compression and anti-rodent capacity, designed mainly for horizontal direct burial, underground cable trenches and pipe galleries.

2. Core Advantages

(1) Superior thermal & electrical performance of XLPE insulation

Long-term allowable operating temperature reaches 90°C, short-circuit withstand temperature up to 250°C. It has higher ampacity than PVC insulated cables with identical cross-section, suitable for densely arranged high-temperature cable trenches and power distribution rooms.
Ultra-low dielectric loss and stable insulation resistance. Electrical performance barely deteriorates with temperature rise, ensuring reliable signal transmission for PLC, DCS, sensors and frequency conversion control loops.
Inherent halogen-free property; WDZ-KYJV22 low-smoke zero-halogen version emits non-toxic, non-corrosive thin smoke during combustion, meeting strict fire protection standards for subways, hospitals and data centers. ZR-KYJV22 flame-retardant grade is available for general fire-demand projects.

(2) Outstanding horizontal mechanical protection from double steel tape armor

This is the core advantage distinguishing it from steel wire armored KYJV32:

Two overlapping galvanized steel tapes form a full surrounding protective layer, delivering powerful resistance against horizontal extrusion, heavy rolling, rock squeezing and external impact. Ideal for direct burial under roads, factory yards and underground pipe galleries.
Excellent anti-rodent and anti-termite performance; steel tape can prevent rodents from biting through the cable insulation.
Good anti-corrosion: Galvanized steel tape resists mild soil corrosion, and the outer PVC sheath provides secondary isolation from damp, slightly acidic/alkaline soil.

(3) Wide environmental adaptability

Strong UV and weather resistance: XLPE insulation avoids rapid aging, pulverization and cracking under long-term sunlight exposure, supporting outdoor open cable tray laying.
Great low-temperature toughness: Remains flexible at -40°C without embrittlement, applicable to cold northern outdoor and underground projects without extra anti-freezing conduits.
Good moisture and mild chemical resistance: Stable operation in damp tunnels, water treatment plants and light-pollution chemical workshops.

(4) Balanced construction performance

Smaller outer diameter and lighter unit weight than steel wire armored KYJV32, lowering load requirements for cable brackets and pipe galleries.
Smaller minimum bending radius than steel wire armored cables, more convenient for turning laying in trenches.
Lower production cost than KYJV32, cost-effective for mass underground horizontal laying projects.

(5) Expandable anti-interference function

Equipped with copper braided shield (KYJVP22) or copper tape shield (KYJVP2-22) to suppress low-frequency magnetic interference and high-frequency radio interference respectively, solving signal distortion caused by inverters, high-power motors and transformers.

3. Disadvantages

(1) Poor vertical tensile capacity

Flat steel tape layers cannot bear large vertical pulling force. It is forbidden for long-distance vertical shaft or suspended overhead laying; KYJV32 steel wire armored cable must be selected for vertical tension scenarios.

(2) Weak anti-twist performance

Steel tape armor is prone to separation and deformation under long-term torsion, not suitable for inclined mine shaft winding laying.

(3) Rigid armor limits ultra-narrow bending

Compared with unarmored KYJV, KYJV22 requires a larger bending radius; it cannot be used for wiring inside compact small control cabinets.

(4) Ordinary XLPE is non-flame-retardant

Basic KYJV22 without flame retardant modification will sustain combustion under open fire; flame-retardant or low-smoke halogen-free customization is mandatory for public high-rise buildings and fire control systems.

4. Common Model Classification

KYJV22: Basic unshielded steel tape armored control cable, for ordinary underground direct burial and horizontal cable trenches.
KYJVP22: Copper wire braided shield + steel tape armor, good at suppressing low-frequency magnetic interference near transformers and heavy motors.
KYJVP2-22: Copper tape shield + steel tape armor, excellent anti-high-frequency interference for automation production lines with many inverters.
ZR-KYJV22 / ZR-KYJVP22: Flame-retardant series, used for fire linkage control circuits of high-rise buildings and underground pipe galleries.
WDZ-KYJV22 / WDZ-KYJVP22: Low-smoke halogen-free flame-retardant type, for subways, hospitals, underground comprehensive pipe corridors and large commercial complexes.

5. Applicable & Inapplicable Scenarios

Suitable Scenarios

Horizontal direct burial under roads, factory yards and green belts
Underground cable trenches, municipal comprehensive pipe galleries, damp tunnels
Outdoor open cable tray horizontal laying in high-temperature or cold industrial zones
Projects requiring anti-rodent, anti-extrusion and anti-impact protection
Industrial automation control loops with mild to medium electromagnetic interference (shielded versions)
Light chemical plants and water treatment workshops with weak soil corrosion

Unsuitable Scenarios

High-rise vertical cable shafts, mine vertical shafts and long-span suspended overhead laying (choose KYJV32 instead)
Inclined winding tunnels with continuous torsion force
Ultra-narrow control cabinets requiring small bending radius and flexible wiring
Low-budget indoor cabinet wiring without underground mechanical protection demand
Environments with strong acid, heavy oil and severe soil corrosion (special anti-corrosion sheath cables are required)
