Financial year
Poles condemned as percent of population
USE OF WOODEN POLES IN OVERHEAD NETWORKS
Lowest cost
Most versatile
Relatively lightweight Renewable resource
MANAGEMENT OF WOODEN POLES (World wide trends)
Increasing focus on maximising life of assets
Change from cyclic to reliability based maintenance
Managing poles preferred to replacing poles
Improved control of pole failures and supply reliability
MANAGEMENT OF WOODEN POLES (continued)
Alignment of inspection, treatment and data collection
Increased use of pole reinstatement systems
Management of poles is no monkey business
HOW PRESCHEM CAN ASSIST THE MANAGEMENT PROCESS
Provide a broad and balanced perspective Experience in most aspects of pole management
Standards Training Treatment Process
Quality Control IT Systems
Ongoing technical support
KEY ASPECTS TO EFFECTIVE POLE INSPECTION
Visual inspection and sounding Target critical zone immediately below groundline Detailed external probing Managed use of boring holes for internal inspection to minimise strength reduction to poles
KEY ASPECTS TO EFFECTIVE POLE INSPECTION (continued)
Critical analysis of shavings from drilling Evaluation of pole strength Capture of information Use of auditing to standardise and improve
USE OF REMEDIAL TREATMENTS
Barrier and diffusible types Preschem products utilise diffusion principle Diffusion occurs at critical moisture levels for decay
External treatment uses a bandage containing solid pills
Internal treatment uses chalk type rods
APPLICATION METHOD FOR POLESAVER RODS
Drill treatment holes around pole circumference Insert several Polesaver rods per hole Plug with suitable tapered plug Screwed plastic plugs and other accessories available from Preschem
APPLICATION METHOD FOR BIOGUARD BANDAGE
Excavate around pole to 300mm deep
Wrap around circumference of pole and tape top section
Measure pole circumference and cut length of bandage
Backfill and consolidate
Clean soil and excess decay from outside of pole
BENEFITS OF SOLID TREATMENTS
Safe and easy to handle Minimum protective equipment required No specialist application equipment Slow release provides longer term effectiveness Minimal environmental contamination
STORAGE AND HANDLING
Not classified as a dangerous good for storage and transport
Clean and can be stored in original boxes Indefinite shelf life
Require dry, cool and well ventilated area
PERFORMANCE TRIALS Many trials already conducted throughout Australia and other countries Trials confirm the effectiveness of the diffusion process used to distribute the actives in Preschem treatments Field conditions are always simulated even to the extent of installing pole caps
PERFORMANCE TRIALS (continued)
Trials also extend to investigating product improvement Most trials have been independently assessed by Government Research Organisations Preschem committed to ongoing long term Research and Development program
ENVIRONMENTAL CONSIDERATIONS
Preschem products are already registered for safe commercial use in several countries Controlled release of actives into wood Minimisation of waste Inaccessibility to public and animals
Preschem utilises an Environmental Management plan which incorporates aspects from production through to the end use of products
COST CONSIDERATIONS
Effective management of the pole population will lead to significant capital replacement savings
Projected Utility Budget Savings

Using typical Australian experience projected over 500,000 poles
COST CONSIDERATIONS(continued)
Minimal equipment needed to install treatments Low cost of inspection Poles can have extended service life of >50 years Pole inspection can assist in effective maintenance planning of other assets Reduction in expensive pole failures and other unplanned failures
HOW PRESCHEM CAN ASSIST IN THE IMPLEMENTATION OF A
POLE MANAGEMENT PROGRAM
Use of pilot studies and trials
Product registration
Development or refinement of standards and procedures
Training programs
Technical support
SUMMARY
A pole management program will extend the life of poles
Managed wooden poles are cost effective
Data from pole inspection is an aid to maintenance planning
Make use of Preschem support
