Type: MÜ I.,
Standard: VSZM TS 06.30/2001. (MSZ EN 61386 except dimensions)
Field of application: Applicable for protection of insulated electrical cables. Installation may be made with building into the wall or concrete by conventional technology and may be installed exposed as well. Tubes are applicable in dry, dusty, contaminated or periodically humid, hazy, vaporous or corrosive vaporous rooms having “C” and “D” classification for inflammable risk (between temperature range of (-5) °C and (+60) °C. It protects cables and tubes on the medium level of mechanical employment. The type of protection will be specified by the properties of pipe network and its accessories and the development of connections. Material: Rigid PVC for electrical use
Colour: grey or brown
Dimensions:
D = nominal diameter (mm)
v = nominal wall thickness (mm)

Execution of Product: Smooth surface outside and inside with round cross-section
Strength properties:
Flexibility: rigid
Compressive strength: on the result of 750 N compression residual flattening (max 10%), the decrease of the outside diameter is less than 25%, there is no crack on the surface
Impact resistance: After treatment at 60 ± 2 °C for 240 hours and then at -5 °C during 2 hours at least 9 from 12 test tubes will not be broken under effect of impact energy of 2 J.
Heat-resistance: 60 ± 2 °C
Ignitability: tubes are hardly inflammable according to V0 and self extinguish
Thermal expansion factor: 7×10-6 1/°C
Electrical properties:
Electrical properties: min. 100 Mohm
Electric strength: Tubes comply with requirements in case of test at 2000 V during 15 min. after immersion in water during 24 hours.
Protection from external effects:
The protective pipe is perfectly dust- and waterproof. The protective tube network with their installed accessories serves his protection according to the joint’s properties (stuffing box, joining, sticking, etc.)
