- 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 minimize 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 loading or discharge, which could lead to the formation of a dangerous spark? Should it have certain certifications (e.g. UL, CSA)?
Cable protection and guiding systems at LAPP consist of a protective cable conduit, a conduit connector and the corresponding accessories. They protect cables perfectly against dust, moisture, mechanical, thermal or chemical influences. Our flexible protective cable conduits are made of plastic, galvanized steel, stainless steel or a combination of these materials. The portfolio also includes parallel corrugated protective cable conduits, large-scale protective cable conduits or resealable protective cable conduits, hoses with a liquid-tight jacket and cable protection hose systems for special applications, e.g. in the Food & Beverage sector or e-mobility. The tools and accessories allow for quick and easy assembly.
What are cable protection and guiding systems?
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.
What types of protective conduit systems are available at LAPP?
Tools and accessories
Metal protective conduit systems
Protective conduit systems, parallel corrugated or resealable , made of plastic
Protective conduit systems for special applications
Metal protective conduit systems with jacket
Plastic protective conduit systems
What components make up a protective conduit system?
A protective conduit system consists of:
- A protective conduit
- A protective conduit connector
- Suitable protective conduit accessories
Good reasons for a protective conduit system
In which cases are protective conduits indispensable and what functions do they perform in detail?
Function 1: Protect cables and wires
- 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 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: bundling, guiding and thus tidying up cables and wires
In this case, protective conduits act like flexible cable ducts:
the wires and cable bundles packed in it are precisely guided along their installation route. This ensures better organization in the application. Cables that are carefully organized 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?
Where are protective conduits used?
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 connectors 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.
On the lookout for the ideal protective conduit
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.
How to find the perfect conduit system at LAPP?
Ask yourself the following questions:
Application area:
- inside
- outside
- potentially in particularly harsh applications
Temperature ranges:
- 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, Polyamid
- Metall
- Kombination
Approvals:
- UL, CSA
- VDE
- DNV
- EHEDG
- DIN EN 45554
- ATEX
- Thread type M, PG or NPT
- Material
- IP protection rating
- Strain relief
3. Then select the accessories you need for the installation.
