LONDON, Nov. 19, 2015 /PRNewswire/ -- The report contains comprehensive quantitative data and qualitative analysis about the towers and poles markets and stock, globally and for all regions and countries.
1. STEEL TOWERS AND POLES INSTALLED BASE ANALYSIS IN UNITS
Base year 2014
- By region and 124 countries, separately for:
- Electricity transmission towers
- Utility poles - Electricity distribution, telecoms, railways
- Wood, concrete, steel, composite
2. STEEL TOWERS AND POLES MARKET DEMAND IN UNITS
Demand in base year 2014, forecast in nominal $ annually 2015 to 2020
- By region and 124 countries, separately for:
- Electricity transmission towers
- Utility poles - Electricity distribution, telecoms, railways
- Wood, concrete, steel, composite
3. STEEL TOWERS AND POLES MARKET DEMAND EX-FACTORY COST $
Demand in base year 2014, forecast in nominal $ annually 2015 to 2020
- By region and 124 countries, separately for:
- Electricity transmission towers
- Utility poles - Electricity distribution, telecoms, railways
Wood, concrete, steel, composite
4. LONG TERM DEMAND CYCLE FOR STEEL TOWERS
Towers commonly have 40 to 60 year lives so the replacement cycle is a long term issue. To determine the demand cycle it is necessary to chart the growth of the tower stock over many decades. StatPlan has charted this, for towers and poles since 1900 and the cycle is plotted to determine the long term demand cycle.
5. EVOLUTION OF THE TRANSMISSON NETWORKS
Length and voltage time series.
6. TYPES OF STEEL TOWER
- Suspension towers
- Tension towers
- Angle suspension towers
- Dead end towers
7. SERVICE LIFE AND MAINTENANCE OF STEEL TOWERS
Maintenance practices have a critical impact on the service life of towers, especially in harsh climate conditions.
8. UTILITY POLES SERVICE LIFE AND REPLACEMENT
Demand depends on new build and replacement. In 1950, 4.3% of demand for utility poles was for replacement, in 2015 that has risen to 62%. Poles have widely varying
service lives depending on material, and for wood poles the wood species, climate conditions and wood protection. The service lives have been established by region
and in some cases for individual countries.
9. JOINT USE OF UTLITY POLES
Joint use by different utilities is a significant factor in the pole market. The protocols for space allocation and standards are outlined.
10. MARKET COMMENTARY FRO UTILITY POLES
Brief market commentary on installed bases and demand for utility poles in 24 countries, with information on numbers and type of pole.
11. TYPES OF UTILITY POLE AND APPLICATIONS
There are many types of pole in use, depending on the purpose. Different types and applications are outlined.
12. ELECTRIC RAILWAY USERS
Railways are a minority but significant users of distribution poles. The networks are outlined, with description of the traction systems. Usage is estimated.
13. CIRCUIT PHASES AND CONDUCTORS
Most distribution networks employ single circuits, whereas transmission networks range from single to multiple circuits. This is an important consideration in specifying
the type and dimensions of towers and poles.
14. RIGHTS OF WAY
Rights of Way (ROW) is a significant cost and can be a serious obstacle in designing networks and specifying equipment.
15. MANUFACTURERS OF TOWERS AND POLES
- Manufacturers of steel towers are listed with brief details.
- Companies manufacturing concrete and steel poles are listed with brief details.
- Companies harvesting and preparing wood poles are listed with brief details.
16. DANGERS & MITIGATION OF DAMAGE TO UTILITY POLES BY BIRDS
Birds constitute a significant threat to poles and to themselves in nesting and perching on wires and poles, and in colliding with energised lines. These accidents not only
harms the birds but causes power outages.
