1. Only insulators evaluated and accepted by Eskom in accordance with DPC34-113 will be procured.
2. Quality assessment of the supplier in accordance with DST34-705.
3. Samples and drawings must be submitted as part of the evaluation.
4. Test certificates from an acceptable authority are required.
5. Imported products may require landing routine and sample tests completed in South Africa, witnessed by Eskom Quality Management.

No specific scoring split, minimum qualifying score, or preference point system is stated in the provided document.

Scope:

• Supply of outdoor low voltage porcelain shackle insulators for power distribution systems up to 3600 V AC.
• Insulators are for use in new or refurbished overhead power lines, and may also be used for maintenance.

Packaging:

• Packaging must protect insulators from handling and storage; must not disintegrate due to wetting/drying.
• Pallets must not exceed 1800 kg gross weight, be suitable for fork lift trucks (two-way entry, reversible), and be numbered/marked with project details.

Storage, transport and handling:

• In accordance with 240-75906867 (DSP 34-550).
• Insulator sheds must be robust to withstand transport, storage, and handling stresses.

Temperature-cycle test: three cycles of immersion in water at 70–75 °C for 20 minutes, then in ice water at ≤7 °C for 20 minutes; insulators must not break, crack, or craze. Puncture test: immerse in insulating oil, apply voltage between a conductor and bolt; no puncture at specified voltages. Mechanical strength test: mount between parallel straps, apply load per Table 1 for 1 minute without damage. Routine electrical test: apply nominal AC voltage, measure leakage current or impedance until constant reading.

The manufacturer/supplier must have access to engineering facilities to provide technical service, information, advice, and after-sales service related to the products.

Quality assessment per DST34-705. All insulators must be visually examined for defects before testing and packaging; defective units must be marked and discarded. Test certificates for routine production tests must be retained by the supplier. Eskom may randomly select delivered insulators for testing; failure of qualifying design tests leads to rejection of all insulators from that supplier until the issue is resolved. Imported products may require landing tests in South Africa, witnessed by Eskom Quality Management. Type, sample, and routine tests are specified with acceptance criteria per Table 1 and IEC 60383.

No specific pricing format, bid security, bonds, guarantees, retention, payment terms, or financial capacity thresholds are stated in the provided document.

This document sets out the standard technical evaluation criteria for Eskom distribution systems hardware and fittings used on overhead lines. It covers the evaluation strategy, method, and criteria, including desktop evaluation, product sample evaluation, and factory assessment. Specific item requirements are in the Technical Schedules attached to each commercial enquiry.

Returnable documents (all must be in the technical section of the submission; inclusion elsewhere is not considered):

• Technical A&B Schedules for each SAP number, completed and signed.
• Deviation Schedule for each SAP number, completed and signed (even if no deviations).
• Approved Manufacturer Drawings for each unique SAP number, with manufacturer name and approval signature.
• Test Report Schedule with copies of stated tests in English, for each SAP number.

Disqualification risks:

• Missing any mandatory returnable at Level 1.
• Missing information will not be requested after the enquiry closing date.
• Technical returnables placed outside the technical section are not assessed.

Progressive evaluation levels, each must be passed to proceed:

• Level 1 Gatekeeper: pass/fail, 100% threshold. All mandatory returnables must be present.
• Level 2 Scoring: 90% threshold (Eskom may reduce to 85% if no supplier meets 90%). Negative marking from a starting score of 100%. Weightings: Schedule B evidence 20%, drawings 15%, completeness of testing evidence 15%, compliance of testing evidence 50%.
• Level 3 Sample Evaluation: 100% threshold. Non-returnable sample assessed against measurable standards from A&B Schedules and drawings.
• Level 4 Factory Assessment and Verification: 80% threshold. Required for manufacturers without 5+ years of prior Eskom supply; discretionary otherwise.

Final results: Non-compliant, Compliant with qualifications, or Fully compliant.

DTI designation requirements must be met before technical evaluation proceeds.

Scope: Supply and delivery of various line hardware items for overhead lines within Eskom Distribution, on an as-and-when-required basis for 5 years.

Specific technical requirements per item are in the Technical Schedules attached to the enquiry, not in this evaluation document.

Compliance standards: Eskom standards, South African National Standards, or international standards where no SA standard exists.

Products are high-risk items; non-compliance can cause serious harm, injury or death, and affect network performance and continuity of supply.

Bidders who are not the OEM must source required technical returnables from the OEM. If production is outsourced, the tenderer retains full accountability.

Evaluation is conducted per SAP number.

Level 1 and Level 2 are evaluated independently by at least two evaluators; disparities resolved by consensus.

Level 3 sample evaluation is also independently evaluated by at least two evaluators.

Level 4 Factory Assessment is conducted as a team with a single result.

If Level 2 score is below 100% but meets threshold, deviations are noted and not penalised again at Level 3.

Sample evaluation may be done at the manufacturing plant for unduly large samples; smaller samples must be delivered to the designated Eskom commercial office within 14 calendar days of request.

Manufacturers with 5+ years of prior Eskom supply may be exempt from Factory Assessment at the team's discretion; new manufacturers are always assessed.

Factory Assessment reviews the manufacturer's structure, organisation, quality process and experience to confirm capability to produce quality products and operate efficiently.

ISO 9001 is a normative reference.

Level 4 Factory Assessment verifies:

• Good manufacturing practices and production technology (degree of automation, precision).
• Technical work instructions and control of technical changes from design to manufacturing.
• Product control system: testing of raw material and finished products, with retained certification.
• Competent production personnel with relevant certifications and training.

If deficiencies are found, the manufacturer must undertake corrective action and demonstrate it to Eskom before the product is acceptable for procurement.

DTI designation: Eskom distribution hardware items are allocated a DTI designation; technical evaluation proceeds only when designation requirements are met.

Quality management: ISO 9001 referenced as a normative standard.

Progressive evaluation levels: Level 1 Gatekeeper (100% pass/fail), Level 2 Scoring (90% threshold, negative marking, may be reduced to 85%), Level 3 Sample (100% threshold), Level 4 Factory Assessment (80% threshold). Final result is Non-compliant, Compliant with qualifications, or Fully compliant.
