Key advantages
- Enable protection of existing cables without rerouting or prolonged disconnection
- Allow local repair of cable pipes
- Increased strength: high ring stiffness and possibility to be laid in trenches under roads, crossings
- Multiple use is possible
- The pipe can be anchored for position fixation
- Vandal-resistant enclosure – lockable to prevent access by unauthorized persons
- Bell-type pipe connection – no need for female-male couplers
- Bell-type pipe connection allows pipe bending up to 15°
- Quick and simple installation. No need for special equipment and tools
- Can be manufactured in a fire-safe design
- Light weight
02 Application area
Mechanical protection of high-voltage cable lines
Intended for mechanical protection of existing power cable lines and communication cables that are in service and cannot be reinstalled for repair or have long-term disconnection, as well as for installation of temporary electrical networks. Can be used for repair of cable ducts.
- Cable protection under roads
- Cable protection under railway tracks
- Cable protection under temporary structures or buildings without foundations
- Cable protection when crossing utility networks and communications
- Protection of temporary networks cables
- Repair of cable ducts
Laying methods
- Open-cut installation
- Open installation
Installation specifics
Pipe closure and fixation of the lower and upper parts are secured by latch-locks.
Pipes are joined with a female-male connection. The effective installed length is 1 m which simplifies split pipe quantity calculations.
Bends in the pipe duct are made at the bell-type joints between pipes. Maximum turn angle in one joint is 15°.
Bends of the pipe duct with small bend radii are performed using MODUL elbows.
Connection with smooth-walled pipes requires transitions.
For installation across water surfaces, flooded areas, and marshy terrain, pontoon floats are used.
Signal marker posts are installed at 100 m intervals and at route turning points.
