ZESCO standardization program commenced with the formation of standards unit in 1997. The program constitutes the following;

1.       Preparation and implementation of standard technical specification.
2.       Preparation and implementation of standards such as quality of services standards
3.       Preparation of standard work procedures.

Participation in national, regional and international standarsation activities that are of    cost benefit to ZESCO (reduced installation time, improved service, both to our existing and new customers). Reliable power supply to our customers due to reduced vandalism.

7.       Satisfy requirements of the quality of supply standard and the quality service
8.

          PROGRESS
    
    ZESCO is currently developing documentation for standards, specification and work
    
    Procedures that will enhance quality of service `to customers, safety of ZESCO
    
    Staff and the public and profitability of the corporation. So far the following
    
    Progress has been made:
    
    TECHNICAL SPECIFICATIONS
    DISTRIBUTION TRANSFORMER SPECIFICATIONS.
    
     
    ZESCO  has re-engineered the  distribution transformer specifications. The new
    
    Specifications, which have already been implemented, have the following benefits
    
    To our customers:
    
    

1.       Reduced installation time.
2.       Reliable power supply due to transformer's Anti Vandalism features (hermetically
3.       sealed with top cover welded) and can be mounted at a higher height which is not easily  accessible to vandals.

     

11 kV AND 33 kV  LIGHTENING ARRESTORS SPECIFICATIONS.

The new specifications, which have been completed and implemented Will reduce rectification of faults due to faulty lightening arrestors from hours to minutes; This is because the specified arrestors are incorporated with a bottom disconnector which acts as an indicator when arrestor is faulty.

 
All suppliers of ZESCO lightening arrestors are now required to conform to the
New specifications.

 
METER BOX SPECIFICATIONS

ZESCO has standard meter box specifications that customers can access. The standard
Meter boxes have the following features:

1. Lockable
2.       
3. Windows through which meter readers can access the readings even if the meter box is locked (improved frequency of     meter readings).
4. Standard dimensions that provide sufficient space to accommodate the meter ,
5. lightening arrestors, miniature circuit breakers (MCB) and the associated cables.    
6. Customers are advised that no meter box will be acceptable that falls below Zesco Ltd specifications.

CONSTRUCTION STANDARD

POLE MOUNTED TRANSFORMER

STANDARD STRUCTURE
There are two standard structure s that have been done:

1. H-POLE STRUCTURE (FOR 200 kVA  TRANSFORMERS).
2. SINGLE POLE STRUCTURE (FOR UPTO 100  kVA TRANSFORMERS).

The existing standard structures have been reviewed due to the improved new transformer specifications.
The new standard structures have the following inherent benefits:

BENEFITS TO LOCAL SUPPLIERS
 
Zesco Standardisation will benefit the local suppliers in that the standard Specifications that are being prepared by ZESCO are also presented at Regional level. Thus once local suppliers meet the ZESCO specifications.They will be automatically producing goods that would be acceptable to utilities in the region. For example ZESCO is currently actively participating in the
development of a regional technical specifications for drop out fuses.
 
WAY FORWARD.
 
Zesco will focus on enhancing resources to change the mind set of Employees in implementation of the new standards that are being developed to enable successful implementation of the customer service Improvement Program.

 
All suppliers of ZESCO transformers are now require to conform to new specifications.
