3. FURTHER REQUIREMENTS:
3.1 There shall be no rivets in the parts that form the current path
3.2 Water shall not be able to accumulate on any part of the equipment nor shall any feature introduce moisture into any component.
3.3 The design shall incorporate all reasonable precautions and provisions for the safety of personnel concerned with the operation and maintenance of the same.
3.4 The current path shall be such that load current shall only flow through high conductive materials such as copper and its alloys. Load current shall not be permitted to flow through ferrous components, springs, or spring-loaded mechanisms.
3.5 All load current paths shall be so designed that the relevant parts of the solid link assembly are capable of carrying the specified rated current without exceeding the permitted temperature rise in SABS IEC 60282-2
3.6 Contacts shall be based on the line contact principle and there shall be no welds on the contact parts. The construction of the Drop out fuse base and the solid link shall ensure their mutual alignment during closure.
3.7 The solid link should have an eye and an operating tongue.
4. MARKING AND IDENTIFICATION
4.1 Markings to conform to SABS IEC 60282-2
4.2 In addition , the following markings must be included : ZESCO Indent No.
3.0 SUPPLIMENTARY NOTES
3.3 Suppliers should give sufficient information including drawings (which must be brief, clear and to the point) on how their drop out fuse designs addresses these requirements. Further, Suppliers may offer better alternatives that are of cost benefits to. It is therefore imperative that schedule "B" is completed by the tenderer. Any deviations/modifications/alternatives specification must be listed in schedule "C." No deviations/modifications/alternatives will be recognised unless they are listed in schedule "C"
3.4 The drawings to be submitted by the tenderer must include the following:
3.4.1 Critical tolerances
3.4.2 Show details of the insulator, the fuse carrier, the solid-link, the upper contact, the lower contact, the cutout base and the bracket for fixing to either wooden or steel cross arm.
3.5 The type tests to be submitted must be those issued by internationally recognised testing authority.
3.6 All salient design details of each item required shall be supplied with the tender.
