Dealing with the 'spider web' of suspended telecommunication cables and power grids

Currently, several major streets in Vinh City such as Lenin Avenue, Le Hong Phong Street, Truong Thi Street, Cao Thang Night Street or the pedestrian area on Ho Tung Mau and Nguyen Van Cu Streets have been invested with tens of billions of VND to bury telecommunication cables and power lines underground under the sidewalks.

Similarly, when investing in and upgrading key routes, Hoang Mai town or Cua Lo town also required units to have plans to bury cables and not automatically use cables hanging from electric poles as before.

The above work contributes positively to the goal of urban beautification, ensuring safety for people when entering the rainy and stormy season; at the same time, saving maintenance costs for electricity and telecommunications service providers, limiting the phenomenon of short circuits and power outages due to objective reasons.

In fact, the plan to bury telecommunications and power cables was approved by the Provincial People's Committee in 2015, but due to limited resources and the lack of investment interest from telecommunications and power companies, the implementation progress was quite slow and the results were modest.

In order to deal with the shortcomings, insecurity and aesthetic loss caused by the situation of electric cables and telecommunication cables hanging like spider webs all over the roads and houses, on September 15, 2022, the People's Committee of Nghe An province issued Decision 2790/QD-UBND approving the Plan for undergrounding and renovating telecommunication cable networks in 2022, 2023 to 2025 for a number of key projects in the province.

Also in this decision, the Provincial People's Committee requires units to organize underground cable car lines through the shared use of existing underground sewer infrastructure or to build new ones, install additional underground sewer lines and underground cables; some routes cannot be completely undergrounded to the cable box and cabinet but must continue to hang cables, so a part of the capacity must be lowered to lower the cable car load for the pole line, contributing to the cable car decoration.

Implementing the above regulations, since June 2022, a number of telecommunications units have coordinated with residential areas to cut off the signal lines leading to each customer's household subscriber, which were as tangled as spider webs before, but have now been replaced by a common line system following the design of the building; a number of other units, along with investing in switching to new generation cables, have buried the cable system underground... Most recently, VNPT Nghe An has constructed an underground cable tank system running parallel to the drainage system along the sidewalk of Le Nin Avenue.

However, with the current situation of tens of thousands of kilometers of telecommunication cables running along the electric pole system; the infrastructure planning is not systematic, so the goal of undergrounding the suspended cable system faces many challenges.

Recently, when Vinh city had a plan to renovate the urban area, upgrade the night street and walking street, it was very difficult to mobilize and call on telecommunications or electricity companies to invest and cooperate in construction. Although the planning orientation of each street was clear, the situation was that as soon as one unit finished the drainage ditch, sidewalk, and lighting, other units came to ask for permission to dig up the road, dig up the sidewalk to install cable equipment...

According to the roadmap, telecommunications enterprises such as Viettel, VNPT, Mobiphone or FPT will sooner or later have to invest in infrastructure to provide services, but due to lack of coordination, each person does it on their own, causing waste of space resources.

In fact, every day in residential areas or on roads, it is not difficult to realize that the infrastructure of cable lines changes continuously, but telecommunications units do not collect them but leave them on electric poles or throw them away right on the rooftops of high-rise buildings, making the already heavy lines even heavier; the buildings are unsanitary and unsafe during rain and storms.

According to a telecommunications company, one of the biggest challenges in underground cable installation is capital investment. Because it is a new generation cable system, the initial investment cost is quite expensive. If the underground cable system and technical boxes are built along the sidewalk, the investment cost is quite large because the land must be cleared. This infrastructure is best invested by the State and then leased to businesses.

Mr. Nguyen Viet Duc - Head of Vinh City Urban Management Department said: Undergrounding cable systems brings many benefits and is a trend of civilized and smart cities. Along with the proposal to continue undergrounding cables on the street, the city is having to strengthen supervision and management so that the underground routes are not re-encroached and cables are not hung again.
