|Supply and Delivery of Telescopic
Linksticks for Masvingo District
TELESCOPIC LINK STICKS
This specification covers the supply and delivery of telescopic link sticks and accessories. All telescopic link sticks shall be made of epoxy resin-impregnated glass fibres wound around and laid lengthwise over a unicellular plastic foam core. The telescopic link stick shall be supplied with a universal disconnect head.
The Supplier shall state name, place and country of manufacture. The Supplier shall state whether or not the telescopic link sticks 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.
Spares as recommended by the manufacturer should be included in the scope of supply.
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 Company and may not subsequently be made responsive by the Tenderer by correction of the non-conformity.
The Zimbabwe Electricity Transmission and Distribution Company may accept any 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
Unless otherwise specified in the Schedule of Requirements, it must be assumed that the electrical system in which the telescopic link sticks will operate is or has:
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 with frequency variation not exceeding 2.5%.
c) The highest system voltage not normally exceeding the nominal system voltage by more than 10%. The nominal system voltages are 33 kV and 11 kV.
Designs should allow for these variations.
4. PARTICULARS OF THE ENVIRONMENT
Telescopic link sticks will operate 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 telescopic link sticks shall be capable of operating under the following environmental conditions.
a) Ambient temperatures:
(i) Maximum: 45 °C
(ii) Minimum: minus 10 °C
(iii) Maximum daily average: 35 °C
Average altitude of 1 500 metres above sea level. The design shall allow for reduced cooling effect due to high altitude.
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 telescopic link sticks which meet all such conditions.
5. LANGUAGE, UNITS AND STANDARDS
All tenders, correspondence, description upon drawings, illustrations or instructions shall be in unambiguous English Language. SI Units of measurements shall be used throughout.
Except where modified by ZETDC’s Specifications, IEC Recommendations (IEC 76) shall apply throughout or British Standards (BS) where they amplify the IEC 76. In the case of conflict between the above stated Standards and this Specification, the ruling of this Specification shall prevail.
7. DESIGN FEATURES
The telescopic link sticks offered shall be made of high density electrical grade fibre glass or epoxy resin-impregnated glass fibres wound around and laid lengthwise over a unicellular plastic foam core. This foam core shall consist of unconnected individual cells containing a low boiling inert material which inhibits moisture absorption and condensation. The unicellular foam shall be bonded to the reinforced walls.
7.2 Electrical Design
The telescopic link stick offered should be capable of use with voltages up to 132kV, and shall be capable of withstanding a voltage stress of 100kV per metre.
The telescopic link stick shall conform to the following dimensions and weight.
|Number of Sections||Extended Length (m)||Maximum Retractable Length (m)||Maximum Weight (kg)|
7.4 Locking Mechanism
The telescopic link sticks shall have spring-loaded plastic buttons to keep the extended tool sections securely locked in position. As each section is extended, the buttons shall pop into place, allowing a firm and secure coupling, enabling working to be done with complete control and confidence. The sections shall not be detachable during operation.
7.5 Finish & Colour
The telescopic link stick shall have a super smooth glossy finish, bright yellow or bright orange in colour.
7.6 Tool Bag
All telescopic link sticks shall be supplied with heavy duty vinyl-impregnated fabric bags. The bags shall be of the same colour as the link sticks. The universal head shall also be supplied with a suitable carry bag
7.7 Universal Head
The telescopic link sticks shall be supplied with a universal head made from heat treated aluminium alloy.
7.8 Manuals and other Accessories
The following manuals and toolkit shall be supplied at time of delivery:
- One operator’s manual/diagram with each telescopic link stick
- Maintenance chart/ booklet for each telescopic link stick showing service points and lubrication intervals and recommended lubricants.
- Manufactures recommended universal tools suitable for use with the telescopic link stick.
A minimum one year warranty shall be provided on all manufacturers’ equipment.
