A shielded and armored cable is a rugged electrical conductor that features both an internal electromagnetic screen and an external mechanical protective layer. This combined construction enables the cable to preserve clear signal and power transmission in electrically noisy environments, while also withstanding severe physical stress, compression, or direct burial underground.

Structural Layer Breakdown

Conductors & Insulation: Copper or aluminum conductors, each insulated with either PVC or XLPE material.

Shielding (Electrical Protection): A screen formed from copper braid, copper tape, or aluminum-mylar foil, designed to capture and divert EMI and RFI.

Inner Sheath (Bedding): A PVC layer that provides cushioning between the shielded cores and the armor, preventing mechanical damage from the metallic reinforcement.

Armor (Mechanical Protection): A robust outer metallic wrap that guards against compression, impact, rodent attack, and tensile forces.

Outer Jacket: A final protective covering made from PVC, Polyurethane, or LSZH, offering resistance to moisture, chemicals, and ultraviolet exposure.

Application

Direct burial

Installed in open trenches for power and data distribution without the need for additional PVC conduits

Petrochemical and refining facilities

Used in processing zones where cables encounter both heavy mechanical equipment and intense electrical interference from large generators

VFD connections

Employed to link heavy industrial motors, effectively containing high-frequency noise while withstanding regular traffic on factory floors

Mining and heavy infrastructure

Deployed in exposed trays or vertical shafts, where they face risks from rock movement, high tension, and potential contact with heavy equipment

Operating Conditions

Voltage Rating: The cable is rated at U0/U = 450/750V.

Thermal Performance: Two thermal classes are available for the conductor's sustained service temperature – 70°C and 95°C. The lower limit for installation temperature is 0°C.

Bend Radius Guidelines: The following minimum values apply (expressed as multiples of cable outer diameter): 6× for unarmored cables, 12× for armored or copper tape shielded types, and 6× for shielded flexible cables.

Product Advantages

Mechanical Protection

Physical resilience: The steel tape armor provides strong mechanical defense against external compression and pulling forces, making it highly suitable for direct burial or installations where physical damage is a risk-applicable to control cable Cu/PVC/SH/PVC 300/500V, Class 5.

Chemical & wear resistance: Thanks to its steel tape armoring, the cable offers good protection against corrosive substances and surface abrasion, making it a reliable choice for aggressive settings such as chemical plants and offshore platforms.

Signal integrity support: The armored construction also contributes to electromagnetic screening, reducing the impact of external interference on signal quality and improving overall transmission dependability.
