PART 2           PRODUCTS
 
2.01     DESIGN
 
A.        Standardization of Fuse Links (Mechanical/Interchangeable).
 
High voltage expulsion fuses shall be suitable for use on the Expulsion fusegears described in the associated specifications H16 and H34.
 
B.        Rating of Fuse Links
 
The preferred rating of fuse links shall be 3A, 5A, 8A, 16A, 25A, 40A, 63A and 100A at 11kV and 1A, 2A, 3A, 5A, 8A, 16A, 20A and 31.5A at 33kV.  The rated current of the fuse link is the maximum current which it will carry continuously without deterioration and undue heating.  Supplier shall state on the attached schedule the maximum temperature in oC attained by the fuse link after continuous operation at maximum rating.
 
C.        Performance Characteristics of Fuse Links
 
1.         The fuse links are required to give protection against short circuits.  They shall be so rated and shall have such blowing characteristics as to be suitable for selective operations with the fuse links at present in use on the system namely Type K i.e. fast, fuse links to NEMA SG2 and ANSI C37.42 1981.
 
2.         The Supplier shall present to the Purchaser timecurrent characteristics of all the distribution fuselinks on offer.  The performance characteristics of the fuselinks shall include:
 
(a)        Meltingtimecurrent characteristics
(b)        Total clearingtimecurrent
 
The timecurrent characteristics shall be presented as curves.
 
The Supplier shall state the minimum and maximum melting currents required to melt the fuse links at the three appropriate time points used in Table 6 {meltingcurrents for TypeK (fast) fuse links) of ANSI C37.42 1981
 
 
2.02       MATERIALS
 
A.        Current carrying Parts of Fuse Links
 
All current carrying parts of the fuse links shall be nonferrous material; the main requirements being resistance to atmospheric corrosion.  Tin is not acceptable as a possible element.
 

Supplier shall state composition of:
 
1.         Fuse Element
 
2.         Fuse Link
 
B.        Fuse Link Button
 
The diameter of the button head cap on fuse links shall be 19.1mm.  Removable type button heads are preferred for use with 11kV fusegear.
 
C.        Length of Fuse Links
 
The minimum overall length of fuse links rated 1 to 100 amperes shall be:
 
:           510mm for 11kV units per ANSI C.37.42
 
:           762mm for 33kV units per ANSI C.37.42
 
D.        Pull on Fuse Links (Tensile Withstand Strength)
 
The expulsion fusegear shall operate satisfactorily while exerting a pull of 44.5N on the fuse link per ANSI C.37.42, 3.2.3.4 1981.
 
E.         Identification
 
Each fuse link must have stamped on it:
 
1.         Manufacturers name or identifying mark
 
2.         Continuous current rating
 
3.         Type designation, K or T
