ZETDC NORTHERN REGION SPECIFICATION
INSULATION GLOVES
1 SCOPE
This specification covers the supply and delivery of Insulation gloves. For the purposes of this specification, Insulation gloves are part of protective equipment for electrical workers.
The Supplier shall state name, place and country of manufacture of Insulation gloves supplied. The Supplier shall state whether or not the Insulation gloves are produced under license, in which case licence holders name shall be stated.
Tenders shall include a complete statement of compliance with this specification and the Technical Guarantee Schedule shall be completed. For every clause in this specification the Tenderer shall state compliance or non-compliance and shall elaborate where appropriate.
2. DETERMINATION OF RESPONSIVENESS
Prior to the detailed evaluation of Tenders, ZETDC will determine whether each Tender is substantially responsive to the requirements of the Tender Document.
For the purpose of this clause, a substantially responsive Tender is one which will conform to all the terms, conditions and specifications of the Tender Document without material deviations or reservations. A material deviation or reservation is one which affects in a substantial way the price, scope, quality, completion, timing or administration of the works undertaken by the Tenderer under the Contract, or which limits in a substantial way, inconsistent with the Tender Document, the Zimbabwe Electricity Transmission and Distribution Company’s rights or the Tenderer’s obligations under the Contract and the rectification of which would affect unfairly the competitive position of other Tenders who have presented substantially responsive Tenders at reasonable price.
A Tender determined to be substantially non-responsive will be rejected by the Authority and may not subsequently be made responsive by the Tenderer by correction of the non-conformity.
The Zimbabwe Electricity Supply Authority may accept any non-material deviation or reservation provided that the acceptance thereof does not prejudice or affect the relative ranking order of any tender in the evaluation of Tenders.
3. PARTICULARS OF THE ELECTRICAL SYSTEM
The Insulation gloves will be used in an electrical system with the following parameters;
a) Three phase overhead-line construction and underground system. The maximum earth fault factor on the network is 1.5.
b) Operated at 50 Hz, with approximately sinusoidal wave form.
c) The highest system voltage does not normally exceed the nominal system voltage by more than 10%. The nominal system voltages are 33 kV and 11 kV.
d) The system frequency variation does not exceed plus or minus 2.5% from 50 Hz.
4. PARTICULARS OF THE ENVIRONMENT
The Insulation gloves will be used within the tropics and will be subjected to sudden ambient air temperature changes of the order of 10 °C per hour, occurring at the onset of rain, but the barometric pressure at any given place does not vary by more than approximately 10mm Mercury. Frequent and severe lightning storms occur during summer months, with isoceraunic levels varying between 50 and 100 thunderstorm days per annum.
The Insulation gloves shall be capable of operating under the following environmental conditions.
a) Ambient temperatures:
(i) Maximum: 40 °C
(ii) Minimum: minus 10 °C
(iii) Maximum daily average: 35 °C
b) Altitude:
Maximum altitude of 1 500 metres above sea level. The design shall allow for reduced cooling effect due to high altitude.
c) Humidity:
Humidity of 13mg per cubic metre absolute and 65% relative before storms with vapour pressure of 17mmHg.
It is the supplier’s responsibility to make himself familiar with any other climatic and physical conditions pertaining in Zimbabwe and to supply earth sets which meet all such conditions.
