Cable protection and guiding systems

Cable protection and guiding systems at LAPP consist of a protective conduit, a conduit gland and the corresponding accessories. They protect cables perfectly against dust, moisture, mechanical, thermal or chemical influences. Our flexible protective conduits are made of plastic, galvanised steel, stainless steel or a combination of these materials.

LAPP's portfolio also includes

• Parallel corrugated protective conduits.
• Large-scale protective conduits or resealable protective conduits.
• Hoses with a liquid-tight sheath.
• Protective conduit systems for special applications, e.g. in the F&B sector or e-mobility.
• Tools and accessories allow for quick and easy assembly.

ANAMET Europe offers globally renowned flexible metallic conduits and fittings that guarantee excellent mechanical protection and flexibility even in the most demanding conditions. ANAMET's Anaconda^® brand is recognized worldwide for its high quality and durability.

ANAMET's solutions serve multiple industries

• Rail Transportation: Certified cable protection supports the industry's sustainability and safety.
• Oil & Gas Industry: Flexible metallic conduits withstand extreme conditions, such as on drilling rigs, desert pipelines, and in refineries.
• Food Industry: Hygienic solutions with extensive approvals including EHEDG, FDA, NSF, Ecolab, IECEx, and ATEX.
• Extreme Environments (Fire Protection): In production facilities for the steel, forging, and glass industries, cables are exposed to extreme conditions, requiring conduits and fittings to offer reliable cable protection to ensure the efficient operation of equipment and machinery.

PMA^®cable protection offers flexible and non-metallic conduit systems designed to safeguard critical electrical and data cables. These solutions are broadly applicable across various industries—ranging from rail transportation and industrial machinery to marine electrical systems, renewable energy, telecommunications, construction, and medical equipment. The PMA^® system ensures reliable protection wherever cables are exposed to mechanical stresses and environmental challenges.

PMA® cable protection key features

• Non-metallic, flexible conduits for critical cables.
• Broad applicability from rail transportation to renewable energy and medical equipment.
• Designed to withstand mechanical stresses and environmental hazards.
• The PMA EcoGuard™ series is made from 50% recycled raw materials. 
• Test methods developed in the PMA laboratory guarantee the highest quality.

A cable protection and guiding system offers you the opportunity to additionally protect your cables and wires and to guide them securely.

At LAPP, this refers to flexible protective conduits.

This guide provides you with information about protective conduits and corresponding accessories for applications according to DIN EN IEC 61386-23 (VDE 0605-23:2021-12): Flexible electrical conduit systems. Our cable protection products do not include pneumatic or hydraulic hoses.

Note:

We offer cable protection and cable guiding systems for automated applications in the form of assembled cable chains under the product name SILVYN® CHAIN.

A protective conduit system consists of:    

• A protective conduit
• A protective conduit gland
• Suitable protective conduit accessories

In which cases are protective cable conduits indispensable and which functions do they perform in detail?

Function 1: Protect cables and wires

Depending on the material and design, protective conduit systems offer:

• Reliable protection against dust, moisture, humidity and UV rays
• Mechanical protection against sharp edges, friction, abrasion or even welding sparks
• Thermal protection against the effects of extreme heat from e.g. flames or liquid metal, or protection against very cold temperatures
• Chemical protection against substances such as those in cleaning agents, solvents, lubricants, oils and petrol etc.
• Protection against electromagnetic interference

Function 2: bundle, guide and thus tidy up cables and wires

In this case, protective cable conduits act like flexible cable ducts:the wires and cable bundles packed in it are precisely guided along their installation route. This ensures better organisation in the application. Cables that are carefully organised not only look better, they also increase occupational safety by reducing trip hazards.

A protective conduit system provides your cables and wires with increased dimensional stability, abrasion resistance, impact resistance, strain relief, flexibility and sealing.

Did you know that it can be more cost-effective to buy a less expensive cable and protect it with a protective conduit, instead of buying a more expensive and stable cable?

Additional cable protection is very important for numerous industrial areas (e.g. mechanical and plant engineering, machine tool construction, the automotive industry, renewable energies, the beverage and food industry), but is also required and used in public buildings, shipbuilding, rail transport and in many outdoor applications.

Depending on the application, protective conduits and conduit glands are made of plastic or metal, or a combination of both materials.

All cable types can generally be protected by a protective conduit wherever additional protection is required due to external influences.

Simple protective conduits are suitable for fixed installation; flexible protective cable conduits, on the other hand, are also suitable for dynamic applications.

Depending on the application, cable protection should have different properties. Not every protective conduit is also suitable for moving applications, can be installed outdoors or in the ground, is liquid-tight or can be mounted at a later date.

What should the ideal protective conduit be able to do in your application?

• Should it be heat-resistant to the effects of flames, hot chips and liquid metal?
• Should it be UV-resistant for outdoor use?
• Should it be halogen-free to meet the standard requirements in public buildings or railway vehicles?
• Should it be oil-resistant in order to be used in oily environments?
• Should it have flame-retardant properties and be self-extinguishing in order to meet defined fire protection requirements?
• Should it be corrosion-resistant to enable frequent product cleaning or underwater use?
• Should it be electromagnetically compatible, i.e. provide protection against electromagnetic radiation and minimise the emission of such radiation?
• Should it be slotted or divisible so that it can be integrated into existing applications at a later date?
• Should it be highly flexible for use in cable chains?
• Should it have an anti-static effect, e.g. in areas at risk of explosion, to prevent static charging or discharging that could lead to the formation of a dangerous spark? Should it have certain certifications (e.g. UL, VDE)?

In addition

Which IP protection class is required for the protective conduit system?

1. First select the protective conduit.

Ask yourself the following questions:

Application range:

• Inside
• Outside
• Potentially in particularly harsh applications

Temperature range:

• Room temperature
• Hot
• Cold

Flexibility:

• Static use
• Flexible use

Filling degree:

For flexible use, a maximum degree of filling of 60 - 65% of the inner diameter should be ensured. This means that the cable should occupy less than two thirds of the space.

Installation:

• Available space
• Required inner/outer diameter

Material:

• PVC, polyamide
• Metal
• Combination

Approval:

• UL, CSA
• VDE
• DNV
• EHEDG
• DIN EN 45545
• ATEX

2. Then select a suitable conduit gland.

Please note the key selection factors:

• Thread type M, PG or NPT
• Material
• IP protection class
• Strain relief

3. Then select the accessories you need for the installation.
