Electrical conduit: Reliable protection for cables and wires from EMC-direct
Electrical conduits reliably protect cables against mechanical, thermal and - depending on the design - weather-related influences. They are used in building installations as well as in industrial applications and outdoors, for example in PV systems. With the right installation conduits, you can ensure that your electrical installation is permanently stable, standard-compliant and efficient.

What is an electrical conduit and what types are there?
An electrical conduit is a plastic conduit, usually PVC or polyolefin (PP, PE, HDPE), specially developed for electrical installations. It protects cables mechanically and facilitates subsequent installation. Technically, a distinction is made between two main types:
As the name suggests, this conduit is rigid and not flexible. It is often used for clean surface-mounted installations in basements or industrial buildings. The rigid, gray electrical conduit is a classic here.
Material-based systems for advanced applications
In addition to the design, the material plays a decisive role, especially outside the classic flush-mounted installation:
- PVC (standard in building installations): Proven for indoor areas, cost-efficient and easy to process.
- Polypropylene (PP): Higher temperature resistance than PVC; fire protection, halogen-free and UV stability are only given in specific versions.
- Polyamide (PA6): Very high mechanical strength, abrasion resistance and temperature resistance - ideal for building installations.
- HDPE (High Density Polyethylene): Corrosion-resistant, flexible and durable - also suitable for outdoor use, depending on the model.
Comparison: Rigid vs. flexible electrical conduits
| Criterion | Rigid electrical conduit | Flexible electrical conduit |
|---|---|---|
| Structure | Smooth, dimensionally stable conduit |
Corrugated conduit with flexible structure |
| Flexibility | Not bendable, fixed shape |
Very flexible, adapts to pipe routes |
| Installation method | Ideal for straight runs in walls, ceilings and concrete |
Ideal for complex routes, cavity walls and post-installations |
| Installation effort | Higher for changes of direction (bends required) |
Quicker to install due to bendability |
| Mechanical stability | Very high, particularly pressure and impact resistant |
Good, but depends on material and design |
| Cable traction | Very possible due to smooth inner wall |
Very well possible with pull-in aid |
| Area of application | New build, industry, visible surface-mounted installation |
Refurbishment, flush-mounted, flexible cable routing |
| Outdoor use | Only with suitable, UV-stabilized variants |
Often more suitable due to adaptability |
| Typical advantage | Clear, stable cable routing and high protective effect |
Maximum flexibility for difficult installation routes |

The most important properties: Compressive strength and diameter
To find the right pipe, the following criteria are decisive:
Diameter
The diameter is specified in mm. Common sizes are 20 mm (M20), M25 or M32. An electrical conduit with a diameter of 20 mm is an all-rounder for many standard applications.
Compressive strength
The following table illustrates the standardized classification system for determining the mechanical and thermal properties of electrical conduits:
| First digit: Compressive strength | Second digit: Impact resistance | Third digit: Min. temp. | Fourth digit: Max. Temp. | Fifth digit: flexibility |
|---|---|---|---|---|
| 1: very light (125N) | 1: 0.5 kg / 100 mm (very light) | 1: +5°C | 1: +60°C | 1: rigid |
| 2: light (320N) | 2: 1.0 kg / 100 mm (Light) | 2: -5°C | 2: +90°C | 2: flexible |
| 3: medium (750N) | 3: 2.0 kg / 100 mm (Medium) | 3: -15°C | 3: +105°C | 3: flexible, self-recovering |
| 4: heavy (1250N) | 4: 2.0 kg / 300 mm (heavy) | 4: -25°C | 4: +120°C | 4: flexible |
| 5: very heavy (4000N) | 5: 6.8 kg / 300 mm (very heavy) | 5: -45°C | 5: +150°C | - |
The advantages of our electrical conduits
Our electrical conduits are specially developed for professional applications and offer comprehensive protection for cables in demanding environments.
- Reliable mechanical protection for cables: Electrical conduits effectively protect cables against abrasion, impacts and dynamic loads, thereby increasing the service life of the entire system.
- High flexibility combined with a stable shape: Flexible electrical conduits are easy to lay and adapt to different conditions, yet retain their shape, enabling clean and safe cable laying - even with complex cable routes.
- Flame-retardant & halogen-free materials: Some variants are flame-retardant and meet important safety requirements for modern electrical installations.
- Quick & easy installation: Flexible designs, slotted variants or reclosable systems enable quick installation and retrofitting of existing cable systems.
- Versatile application options: The electrical installation conduits are suitable for indoor and outdoor areas, for building installations, industrial applications and especially for cabling photovoltaic systems.

Standards & safety for electrical installation conduits
Electrical installation conduits must meet certain safety and quality requirements to ensure that the cables are reliably protected in the long term.
The basis for installation includes EN 61386, which specifies the requirements for conduit systems for cable routing - including aspects such as pressure resistance, temperature resistance and flame resistance - as well as DIN VDE 0100, which regulates the safe installation of electrical cables as a whole. In particular, it defines how cables must be protected, routed and secured against external influences. In addition, requirements for flame retardancy, mechanical stability and temperature resistance play an important role.
For you, this means
- Electrical installation conduits must be sufficiently pressure and impact resistant, depending on where they are used.
- Flame-retardant properties increase safety, especially for installations on buildings.
