gabo Systemtechnik Laying instructions. 5 speed•pipe® bundle SRV 50 / 8 x 10 Protection from contamination and mechanical damage. The speed•pipe® bundle SRV and the internal speed•pipe® must be protected against contamination and mechanical damage during transport, storage and processing. Avoid damage and distortion. Any damage and distortion of the speed•pipe® (ovalisation) must be avoided as it can cause a decrease in the blowing distance of the micro cables. The speed•pipe® ends must be protected against the penetration of dirt and water by means of dust covers, end plugs ES or sealing elements EZA-t. dust covers: protection against dust, dirt and splashing water, not pressure-tight end plugs: pressure-tight up to 0.5 bar sealing elements: pressure-tight up to 0.5 bar The SRV and the speed•pipe® are UV-resistant (3 years southern european climate). When storing them over a long period of time (several months) the SRV must be protected against direct solar radiation. Overview. First indications. Please note: The laying instructions are important for the correct completion of construction and installation work.
gabo Systemtechnik Laying instructions. 6 speed•pipe® bundle SRV 50 / 8 x 10 Laying event at temperatures of 10 °C below zero. The high-quality material PE-HD of the speed•pipe® and the jacket pipe allows the laying event at temperatures of 10 °C below zero. Optimum at temperatures between 5 and 20 °C. However, the optimum conditions are obtained at temperatures between 5 to 20 °C. At temperatures below the freezing point, store in heated areas. At temperatures below the freezing point we recommend to store the coils with the SRV before laying in heated areas for 12 to 24 hours. When preparing fitting lengths please pay attention to the temperature-induced change in length of the ducts. If the temperature of the duct wall increases or decreases by 1 Kelvin (1 K = 1 °C) the PE-HD duct shall extend or shorten by 0.2 mm per meter length. Thus, the duct shortens by 1 mm in case of a temperature difference of Δ -5 Kelvin. Laying and notes. 2. Laying temperatures. In the construction of all kind new fibre optic routes, to avoid tension in the duct system particularly in midsummer the duct string must be placed in the trench some time before it is filled, to reach an adaption between duct and soil.

Laying aids at a glance Manhole edge roller Cable-protection bow 1) Cleaning the conduit KKR. 2) Testing and calibrating the ability to penetrate of the KKR. 3) Placing the laying carriage with SRV 50 / 8 x 10 in a linear direction to the manhole. 4) Use laying tools to avoid any damage of the jacket pipe (e. g. edge roller at the manhole, cable-protection bow). FIRST STEPS:
gabo Systemtechnik Laying instructions. 12 speed•pipe® bundle SRV 50 / 8 x 10 Laying instructions. 6.2 Installation of the pulling grip. 1) Gradate speed•pipe® and jacket pipe to achieve a uniform force distribution on the entire SRV: cut back the jacket pipe for approx. 500 mm. crosscut the speed•pipe® in 70 mm gradations. 2) Seal the single speed•pipe® against the penetration of dirt and water with end plugs ES 10. 3) Bend the end of jacket pipe around the speed•pipe® and fix it with fabric tape. 4) Pull the pulling grip (Ø 50) onto the jacket pipe of the speed•pipe® bundle and fix it with fabric tape (bend respectively approx. 10 cm over pulling grip and jacket pipe). recommended product: transparent permanent end plugs
gabo Systemtechnik Laying instructions. 13 speed•pipe® bundle SRV 50 / 8 x 10 1) Pulling a piece of jacket pipe onto the pulling grip. 2) Wrap glass-fabric tape or similar round the ends of the coated jacket pipe. Please note: For reducing the friction during the pulling process, additionally a piece of jacket pipe can be attached onto the pulling grip.
gabo Systemtechnik Laying instructions. 14 speed•pipe® bundle SRV 50 / 8 x 10 Laying instructions. 6.3 Pulling in the speed•pipe® bundle SRV 50 / 8 x 10. • The speed•pipe® bundle SRV 50 / 8 x 10 is pulled in by means of a traction rope or a tube snake. • Assistance at the coil end may be required as well as at the launching / pulling manhole. • It is to be avoided that the speed•pipe® bundle is placed at the direct access area of the manholes. Therefore, consider the deflection (see page 17) at drawn through or connected SRV. • In case of short distances between the manholes the SRV can be drawn through using protective sheets and pulling spouts. • In case the KKR is to be occupied with two speed•pipe® bundles, these can be pulled in one after the other or at the same time. • The use of lubricant (e. g. Polywater J-19 V Gel; Polywater SP – 128 V Flu) is reducing the pulling in friction.

Laying instructions. 6.7 Connecting the SRV in the cable duct. Please note: After having fixed the SRV in the KKR 110, the bundle must be deflected in the manhole in a way that it doesn’t obstruct further infeed and extracting works and that there is no risk of damage during these works. Additionally, the speed•pipe® bundle must not be placed in the direct access area of the manhole. With regard to the blowing in lengths choose quite wide bending radii! LAYING INSTRUCTIONS: 1) Cut both jacket pipes (together at least 1 m). 2) Seal both ends of the bundle with EZA-t 50 / 8 x 10. 3) Afterwards cut the single speed•pipe® each shifted for at least 120 mm. A straight, right-angled cut to the pipe axis is observed! 4) Connect the speed•pipe® of the same colour with DSM 10.

For blowing in micro cables into the speed•pipe® that are integrated in the SRV we recommend a blowing in pressure up to 15 bar at speed•pipe®. Optimum blowing in values are reached at a temperature range from 5 to 20 °C. The cable to be blown in must not be exposed to direct solar radiation. It might also be helpful to use lubricants that are tested and recommended by specialist companies (e. g. Micro-Jettinglube, Vetter). 8 % blowing in team 15 % cables 20 % route planing 7 % weather (temperatures, humidity) 20 % laying (installation) 15 % micro ducts 15 % blowing in equipment (compressor, blowing in device, winding up of cables, lubricant) The blowing in lengths to be achieved depend on several factors.
