• Details of the proposed conductor identification system and cable identification system, submitted for Eskom approval.
• Any deviation from the requirements set out in Schedule A must be recorded in the deviation schedule.
• A blank entry in Schedule B against a requirement listed in Schedule A is treated as confirmation that the bidder does not comply with that requirement.
• Price schedules must be drawn up so that the cost of all services, including testing and delivery, is declared and allowed for in the bid.

Technical evaluation

• Documentation required at tender: cable dimensional data (diameters over conductor, insulation, bedding, armour and outer sheath, plus insulation thickness); ratings (maximum sustained current in ground, air and ducts, short-circuit ratings, mass per metre, gross mass per standard drum, 50 Hz a.c. resistance, reactance per phase, capacitance per phase and zero-sequence impedance and capacitance); and test reports.

Controls and instrumentation (240-129686484)

• Sets the minimum level of automation expected at Eskom power plants, covering control system hierarchy, analogue and binary control levels, unit start-up and shut-down sequencing, plant control modes and unit co-ordination.
• Applies to unitised (boiler and turbine) and balance-of-plant control systems for greenfield and brownfield projects. Examples are given for supercritical boilers, but the requirements also apply to drum-type boilers.

Performance guarantees

• Product and workmanship guarantees for the applied coating system must be provided at tender stage by the supplier acting on behalf of both the manufacturer and the installer.
• Minimum guarantee period: 15 years.

Registration and statutory

• Registration on the Central Supplier Database (CSD).
• Valid SARS tax clearance / tax compliance status PIN.

Quality and certification

• A formally documented and implemented quality management system meeting at least ISO 9001 (ISO 9002 is referenced in the standard).
• Eskom may audit the quality management system for suitability and effectiveness, and may verify goods for conformance before delivery.
• Cables supplied must bear the SABS mark.
• Compliance with Eskom standards 240-56063805 (LV power and control cable) and 240-129686484 (power plant controls and instrumentation) is mandatory.
• Cable testing must be in accordance with SANS 1507.
• Any deviation from the specified requirements constitutes non-conformance.

Acceptance of LV power and control cables is based on the technical evaluation criteria applicable at the time of tender and on factory acceptance testing as required by the cable standard.
