The MEA Governor said that cable wiring problem caused by illegal tapping and non-standard installation has imposed an eyesore on the landscapes including accidents, for example, untidy cables have been knocked down in traffic accidents causing power poles to collapse and burn which affected the power distribution system and public safety. As an agency responsible for maintaining the power system and electrical distribution equipment in Bangkok, Nonthaburi and Samut Prakan, MEA always works hard to find a solution. Recently, MEA has succeeded in employing new technology to group telecom cables into a Microduct. The pilot project has been running on the north side of Rajavithi Road, even number alleys (from Khao Road Intersection to Kanruen Intersection), a distance of 730 meters during August - October 2018. Once completed, it will help solve the problem while supporting a large number of cables and keeping them under control.
The SOCC (Single Overhead Communication Cable) techniques have been used by applying the Aerial Microduct for underground cables to be installed on the power poles and using the Air Blown System to push cables into a pipe. The Microduct has special qualifications for being a Messenger Wire with a high tensile strength of FRP (Fiber/Fiberglass Reinforce Plastic), precluding the use of steel or wire rope and installing by attaching to the poles. When the accident occurred, the Microduct will not break, so the poles will not collapse or fall. The 3.5-cm diameter can accommodate up to 672 core fiber optic cables, which is enough to support the existing 168-core cables. Upon completion of the installation, the old cables will be dismantled, leaving only one Microduct on the poles. The operational sequence consists of: 1) Installing the Aerial Microduct, 2) Installing the Outdoor Cabinet, 3) Installing the Air Blow Cable, and 4) Connecting cables for use by telecom agencies and operators.
For the future Microduct projects, MEA has set up operational plans for 7 routes:
1. Sathorn Road (Charoenkrung Road Intersection - Rama IV Road Intersection): 3.6 km
2. Rama IV Road (Rajdamri Road Intersection - Klongtoey Sub-Power Station): 2.3 km
3. Sarasin Road (Rajdamri Road Intersection - Wireless Road Intersection): 0.8 km
4. Chidlom Road (Phetchaburi Road Intersection - Ploenchit Road Intersection): 0.7 km
5. Langsuan Road (Ploenchit Road Intersection - Sarasin Road Intersection): 1.3 km
6. Charoenrat Road (Rama III Road Intersection - Sathorn Road Intersection): 3.8 km
7. Henri Dunant Road (Rama I Road Intersection - Rama IV Road Intersection): 1.8 km
The total distance is 14.3 km., which will cost 600,000 baht per 1 km.
MEA will coordinate with telecom operators and relevant agencies. A mutual collaboration is being conducted to tackle the cable problem by using the Microduct technology. After completion, it will help build a stable power system and beautify the city as a Smart Metro while demonstrating MEA as a leader to pass on the technology to solve the messy-cable problem in Thailand.
