What Is a Wiska ShieldGLAND?

Wiska ShieldGLAND is a specialist cable gland system developed for suitable armoured, SY, CY and non-armoured cables. It combines sealing and cable clamping functions with components designed for different cable constructions.

Wiska positions ShieldGLAND as an alternative to conventional BW and CW gland arrangements for specified applications. A polyamide outer section provides a finished protective covering, removing the need for a separate conventional shroud in the manufacturer’s intended installation arrangement.

However, a ShieldGLAND is not automatically compatible with every cable or enclosure. The exact version, cable dimensions, armour or screen construction and any earthing requirements must be checked before installation.

How Does the ShieldGLAND Clamping System Work?

A distinctive feature of ShieldGLAND is its adaptable clamping olive. Wiska describes how the clamping arrangement can be configured for compatible armoured or SY/CY cable constructions.

Its two-part sealing gasket can also accommodate different specified cable diameter ranges, with an inner sealing insert that may be retained or removed according to the relevant manufacturer’s instructions.

This does not mean the sealing insert should be removed whenever fitting a smaller or larger cable. The correct configuration depends on the exact gland and cable measurements.

Always follow the ShieldGLAND fitting instructions for the selected model, including the positioning of the clamping olive, preparation of the cable and tightening of gland components.

SWA, SY, CY and Non-Armoured Cable Compatibility

Steel Wire Armoured Cable

For compatible SWA cable, ShieldGLAND provides a designated clamping arrangement for the armour. The appropriate gland size depends on the cable’s overall diameter and armour construction.

Protective earthing and armour continuity must be addressed according to the electrical design, applicable requirements and the manufacturer’s approved installation arrangement.

SY and CY Screened Cables

Wiska also specifies ShieldGLAND for compatible SY and CY cable constructions. The adaptable clamping arrangement allows the selected gland to accommodate supported braiding or screening configurations.

Where electromagnetic compatibility (EMC) or screen continuity is required, the complete cable-screen termination must be designed and verified accordingly. Simply fitting a gland does not guarantee a particular level of EMC performance for the finished installation.

Non-Armoured Cables

The ShieldGLAND range can also accommodate selected non-armoured cables within the manufacturer’s specified diameter and configuration limits.

For straightforward non-armoured cable entry without specialist armour or screen requirements, a conventional Wiska polyamide cable gland may be a more appropriate choice.

Cable Screening vs Protective Earthing – Why the Difference Matters

Screening and protective earthing serve different purposes, even though both may involve conductive parts of a cable and its termination.

Protective earthing provides a safety-related connection as required by the electrical installation design.
Armour continuity concerns the electrical continuity of a metallic cable armour and its specified termination arrangement.
Cable-screen termination addresses the connection of a conductive screen or braid, often as part of an EMC strategy.

The requirements can overlap, but they should not be treated as interchangeable. A screened cable does not automatically provide an acceptable protective conductor, and a suitable protective earth connection does not, by itself, guarantee effective high-frequency screening.

For critical control, automation or industrial installations, follow the equipment manufacturer’s EMC and earthing instructions as well as the applicable electrical installation requirements.

Wiska ShieldGLAND Standard, Pro and Elite

The current Wiska ShieldGLAND family includes Standard, Pro and Elite ranges. Their supplied components and intended arrangements differ, so the exact version should be checked before ordering.

For example, Wiska specifies the ShieldGLAND Pro M20S with a brass locknut, E-SPRING and earth fly lead. Do not assume that every ShieldGLAND variant includes these components.

The manufacturer’s ShieldGLAND product information provides the current range distinctions and links to the individual technical specifications.

Wiska ShieldGLAND Sizes and Cable Diameter Ranges

ShieldGLAND is available in several metric sizes. For the manufacturer’s current Standard range, the listed overall cable diameter ranges are:

M20S – 7 to 16 mm cable diameter.
M20L – 12 to 21 mm cable diameter.
M25 – 17 to 28 mm cable diameter.
M32 – 24 to 36 mm cable diameter.

These are the published overall cable diameter ranges for the specified Standard products. The dimensions of the armour or screen beneath the cable sheath must also be checked against the selected gland’s requirements.

M20S and M20L both use an M20 connection thread but accept different cable diameters. Selecting a gland from the enclosure thread alone can therefore result in an unsuitable termination.

Refer to the official ShieldGLAND Standard sizing specifications before selecting the required product.

What Does ShieldGLAND IP68 Protection Mean?

IP68 indicates dust-tight protection and resistance to water immersion under manufacturer-specified test conditions. It should not be interpreted as unlimited waterproofing or suitability for every submerged installation.

Wiska specifies IP68 at 5 bar for 30 minutes for its current ShieldGLAND Standard and Pro products. Earlier CUPG variants have different published test conditions, so the exact model data must be consulted.

An IP68-rated gland does not automatically give the complete electrical enclosure an IP68 rating. The protection achieved depends on the cable, gland, enclosure, seals and installation method.

Why Does ShieldGLAND Not Require a Separate Shroud?

Conventional brass SWA cable gland arrangements may use an external shroud as part of the specified installation. ShieldGLAND incorporates a polyamide outer section designed to provide the required external covering within the manufacturer’s gland system.

This can reduce the number of separate components and simplify the finished appearance of the termination.

However, the shroud-free design should not be confused with a guarantee that ShieldGLAND is suitable for every application where a conventional BW or CW gland might be specified.

Using ShieldGLAND with Wiska COMBI Boxes

Wiska designed ShieldGLAND to work with suitable products from its COMBI junction box range.

Before combining the two products, check the COMBI enclosure’s available threaded entries, wall thickness, internal clearance and specified installation arrangements.

For SWA installations, consider whether the selected enclosure provides sufficient internal space for the cable termination and any required earthing connections. A larger COMBI enclosure may be preferable when several armoured cables are involved.

Our Wiska COMBI buying guide explains the available enclosure sizes and their different entry arrangements.

ShieldGLAND Installation Checklist

Always use the instructions supplied for the specific ShieldGLAND variant. The following checklist highlights the main points to verify before and during installation.

Confirm the cable construction: SWA, SY, CY or compatible non-armoured type.
Measure the cable’s overall outside diameter and check the relevant armour or screen dimensions.
Select the correct gland thread and sealing range.
Use the clamping olive configuration specified for the cable construction.
Retain or remove the sealing insert only as permitted by the manufacturer’s instructions.
Prepare the cable sheath, armour or braid to the manufacturer’s specified dimensions.
Use the supplied or specified earthing components where required.
Follow the specified tightening sequence and torque requirements.
Check cable retention, sealing, continuity and the completed installation.

Do not treat this general checklist as a replacement for the manufacturer’s fitting instructions. Electrical installation work must be undertaken by a suitably competent person using appropriate safe-working procedures.

Common ShieldGLAND Selection and Installation Mistakes

Choosing M20S or M20L from thread size alone without checking the cable diameter.
Assuming any ShieldGLAND configuration fits every SWA, SY or CY cable.
Using the wrong clamping olive arrangement for the selected cable construction.
Removing the sealing insert without checking the approved cable diameter range.
Assuming every ShieldGLAND version includes an E-SPRING and earth fly lead.
Confusing EMC screening with protective earthing.
Assuming the finished enclosure automatically becomes IP68 because the gland is IP68 rated.
Failing to verify the cable preparation dimensions and specified tightening method.
