Objectives

The primary objective of this tender is to procure and supply insulation piercing connectors (IPCs) and associated components for City Power's network infrastructure. The aim is to ensure the provision of high-quality, compliant, and reliable connectors and joints that meet specified standards for various conductor sizes and applications, including main, service, street lighting, and jointing systems.

Scope

The scope encompasses the supply, delivery, and certification of a range of IPCs, lugs, joints, and end caps for low-voltage aerial bundled conductors (ABC). It includes:

• Manufacture and supply of IPCs for different sizes and configurations (e.g., main-to-main, main-to-service, street lighting).
• Supply of bi-metallic insulated lugs and joints for various conductor sizes (25mm² to 120mm²).
• Provision of end caps for conductor protection.
• Compliance with relevant standards such as NRS 018-5, SANS 1418, and NRS 063.
• Provision of certification, technical data, and documentation.
• Training and quality assurance requirements.

The scope excludes installation, but covers delivery to specified locations and certification processes.

Technical Requirements

The technical specifications include:

• Manufacturing standards: NRS 018-5, SANS 1418, NRS 063.
• Product features: waterproof, UV stabilized, marked and packed per standards, supplied with end caps and test certificates.
• Design and certification: type test certificates for electrical aging, weathering, corrosion, fire retardation, shear-head torque, waterproofing, and visual inspection.
• Material specifications: bi-metallic construction for lugs, insulated and UV protected, with specified minimum breaking forces.
• Component sizes: IPCs for conductor sizes 25-95/25-95, 25-95/10-16, 25-95/1.5-6, 120/120, 120/10-16; lugs and joints for sizes 25mm² to 120mm².
• Marking, labelling, and packaging as per standards.

Skills and Skills Requirements

The successful bidder must demonstrate:

• Proven manufacturing capability adhering to relevant standards (NRS 018-5, SANS 1418, NRS 063).
• Experience in producing electrical connectors, joints, and accessories for low-voltage overhead systems.
• Ability to provide comprehensive type test certificates and technical documentation.
• Capability to offer certified training on handling, storage, and installation of the products.
• Implementation of quality management systems compliant with ISO 9001:2015.
• Environmental management practices aligned with ISO 14001 standards.
• Capacity to meet delivery timelines and provide ongoing technical support.

Summary

This tender seeks a qualified supplier capable of delivering high-quality, standards-compliant insulation piercing connectors and accessories, supported by appropriate certification, technical data, and training. The supplier must demonstrate technical expertise, manufacturing capacity, and quality assurance processes to meet City Power’s network requirements.
