Large pipes would affect the natural scenery. 2. Color Grey TFP are recommended for surface installations. During grey TFP production, UV-resistant antiaging agent is added to the material. Color durability of grey TFP is also improved. Grey color also harmonizes better with the electric equipment surrounding.

Cable installations on bridges or embedded in concrete with a space limited by its structure 1. Size of pipe Note: The pipe inner diameter shall be at least 1.5 time the overall diameter of the power cable accomodated. In order to avoid bad effect on bridge concrete construction, it is important to consider the outside diameter of pipes to be installed. For instance, instead of straight Þ48 PVC pipes, TFP Þ50/40 can be used, without causing difficulty to pulling cable in or impairing heat dissipation from cables. Due to their corrugated configuration, TFP also present some other advantages: higher adherence to concrete TFP up to 200m long are available (on order), minimizing the number of joints to be made in concrete. TFP joints are sturdy and water-tight. TFP endure well concrete compacting and hard impacts, excluding risk of ingression of water and other foreign matters. Available pilot wire makes it easy to pull in cables. Low friction reduces risk of cable straining. 2. Color Orange TFP should be used. 3. Fittings 1. Sealing tape, Vulco tape, PVC tape 2.

Please refer to "Instructions for installation" for implementation procedures of 110 - 220 kV underground installations. TFP for 110 - 220 kV installations feature some additional performance: Coils of TFP Þ230/175 and Þ260/200 are manufactured with a length up to 100 m, reducing the pipe joints to be made. Two PVC-covered galvanized steel Þ3.2 mm pilot wires, of a 10 years' durability in natural climatic conditions, are readily supplied. 1. Size of pipe TFP Þ230/175 or TFP Þ260/200 are used. 2.

Bellmouths, waterproof caps are used as instructed. Two Þ3.2 mm pilot wires or a Þ4 mm steel cable should be used to draw cable-pulling wires through TFP conduits.

For TFP of a diameter up to 80 mm, a steel wire 1.6 mm covered with a plastic layer at least 0.2 mm thick is provied inside. For TFP of a diameter of 100 mm and larger, a steel wire of 20 mm covered with a 0.3 mm plastic layer is provided inside. Some notes on pilot wires readily provided in TFP: 1. Use the provided pilot wire only for pulling in power cables of an outer diameter up to 20 mm. 2. If the outer diameter of the power cable is larger than 20 mm, but smaller than 50 mm, use a nylon cord with a diameter of 6 mm or larger, instead of the provided pilot wire, to pull the power cable in. 3. In case the outer diameter of the power cable is larger than 50 mm, please use a PVC-covered fine steel cable of a diameter of Þ3 mm to Þ16 mm, depending on the weight of the power cable to be accomodated. 4.

TFP, if used as a power cable duct, shall be laid in accordance with the requirements prescribed in the Code for Electric Installation and in other applicable regulations. At construction sites, therefore, TFP should be laid in accordance with the stan- dardized laying procedures described below. Trenching The trench cross section is determined by the number of conduits to be laid. This cross section should be determined with considerations of economy and safety associated with the laying operation. It is necessary to follow all safety procedures so that landslides do not occur at the min- imum cross section. The lowermost TFP shall not be laid directly on rocks or pebbles. The trench bottom shall be leveled and then covered with sand before laying TFP.

Laying TFP should be laid with care so as to prevent soil, sand and water from entering through their ends. If the TFP delivered to the site are wound in coils, their laying shall be made in accordance with the following procedure. The TFP coil shall be unwound by rolling it along the trench, held by three or four workers to avoid deformation. If pulled along without being rolled, TFP will twist.

  47. 47. TFP arrangement and sand filling When two or more TFP conduits are to be laid in parallel in the same trench, they should be arranged with the specified distances as shown in Fig A. To this end, a simple gauge shown in Fig B should be prepared to straighten the laid TFP every three or four meters. The straightened TFP should be then held in place with sand or equivalent means, and the gauge should be removed. Passing test rod When laid completely, TFP should be checked for straightness and internal void. Test rods should be selected according to the size of TFP. Passing of test rods is recommended in provisional burying and when TFP systems are laid completely. Filling After conduits are checked for void by passing a test rod through them, fill in the trench to complete the laying. Cable pulling-in Cables should be then pulled into TFP by using the pilot wire previously accomodated in the TFP. The pilot wire should be used only to draw cable-pulling wires through TFP conduits. When concrete buffers are used When buffers are used in TFP arranging, installation should be carried on with the following steps: 1. Place buffers in line along the trench, at specified distances. 2. Lay TFP on the whole tract. The TFP may not be properly arranged at first and need further alignment. 3. Secure conduits on the whole tract to buffers using nylon cord. 4. Composite connectors shall be used for joining TFP accomodating 110 kV or 220 kV power cables. For medium and low voltage cables or telecommunication cables, plastic connectors or joint sleeves should be used. TFP joining work shall be carried on under supervision of site technicians. 5. Proceed to final alignment. 6. Check the conduits for straightness and void, using a test rod. 7. Fill back the trench when all the above steps are completed. - Filling with sand: Sand is poured gradually, filling the trench from its bottom to higher layers. - Filling with concrete: In mechanized concrete pouring, the filling should be made in two steps. First, concrete is poured up to half the height of the conduits. The second concrete pouring is made 3 - 5 hours later, when the last concrete has hardened, up to the specified level. Manual concrete pouring is used when work volume is small. The concrete filling may be made continuously, in one step.

Notes on conduit installations on bridges - Arrange TFP conduits well aligned, close to metallic structures of the bridge. - Secure tightly TFP conduits to metallic structures using wires so that they will not be displaced during concrete pouring. - Seal TFP joints carefully using vul-co tapes to prevent water and concrete from entering conduits. - Special supervision is needed: + During TFP laying: TFP shall be moved away from locations where welding work is taking place to avoid possible damage caused by hot welding scales. + During concrete compacting: When using vibrators, avoid poking them on TFP, which would break TFP-securing ties or pierce TFP. - TFP ends embedded in handholes should be provided with bellmouths to prevent cables from being scratched and damaged during pulling them through the TFP. Because of the fact that a large number of handholes are included in lighting systems on bridges, this requirement is strongly recommended. - Bridge constructions include expansion joints to account for thermal expansion and vibration, which can reach 65mm. Hyundai pipes should be used as conduits crossing these joints. BaAn has the exclsive right to supply Hyundai pipes in Vietnam.
