High Voltage Shielded Cable

Product Description

HVSC Plus is designed and developed to handle lightning transients. The design feature of this concentric conductor involves annular design production with the use of cylindrical filler material for the inner conductor. It is possible to optimize the design in order to carry high-frequency/ transient currents, which are lower inductance and allowance for the Skin effect. The size of inner conductor's cross-sectional area complies with all lightning protection international standards. An insulation layer of adequate thickness can withstand voltages of a pre-specified level, surrounded by thin semi conductive, stress-control layers applied during a triple extrusion production process. Electrical fields are screened by conductive, copper-tape outer screen layer. Cable during handling, installation and in-service period is protected by PVC outer sheath or jacket. It can be installed to any type of structure, be it masonry, non-conductive, metallic or any other. It's performance will not be affected by the structure type.

There are two known geometries in which the voltage within the cables are divided, and these are:

• Between the inner conductor and the screen
• Between the screen and the structure
• It is important to understand the cable parameters to control these voltages, for instance capacitance, inductance, phase velocity and impedance.

The overall diameter of cable is approximately 36 mm. Following are the components of HVSC Plus cable from the inside to the outside:

• Solid, cylindrical, polyethylene filler
• Inner conductor comprising copper strands (XSA 70 mm2)
• Binder tape
• Semi conductive stress-relief layer (conductor screen)
• Polyethylene insulation (approximately 5 mm thick)
• Semi conductive stress-relief layer (insulation screen)
• Copper tape main screen
• PVC outer sheath

Here are the steps to be followed in order to install cable:

• During installation, it is important that it is adequately terminated at the upper end specific cut lengths of the several layers and then a high-voltage termination kit must be used.
• It must be electrically shorted from inner-to-screen connection at the bottom end and bonded to the structure's base.
• Its installation must not infringe on the minimum bend radius criterion.

Exceptional Fire and Environmental Resistance

Engineered to meet IEC 60332-1 for fire resistance and IEC 60811 for oil resistance, this high voltage shielded cable ensures continued performance even in critical environments. The UV-resistant, IP68 water-rated, and flame-retardant design delivers reliability for both indoor and outdoor installations, minimizing maintenance and improving safety in industrial settings.


Advanced Shielding and Dielectric Strength

With over 85% copper braid coverage, these cables provide excellent electromagnetic shielding, maintaining signal integrity even in high-interference environments. The XLPE insulation boasts a dielectric strength of 15 kV/mm, supporting secure power transmission in high voltage applications up to 33 kV.


Customizable Design and Precision Manufacturing

Offered in custom sizes, lengths, and configurations (single or multi-core), this cable can be precisely tailored to specific needs. Each cable undergoes laser marking for clear identification and includes options for galvanized steel armoring and flexible stranded copper conductors, ensuring ease of installation and long service life.
