Distribution Hoostick (DHS)
The next generation of distribution class hookstick switches. Our engineers have developed a modern switch that meets the needs for a versatile, light weight, reliable and economical method of distribution system isolation for utilities. The “DHS” is available in a 30 degrees inclined mounting position, with provision for surge arrester. In addition, the “DHS” can be cluster mounted for three phase applications on one bracket for quick install and compact configuration. The “DHS” is rated to 900A current capacity, 40kA momentary current. The “DHS” switch can be used in the system for isolating or sectionalizing for applications 15kV to 35kV.
PRODUCT FEATURES
Cycloaliphatic epoxy insulators
Copper current carrying parts
Silver-to-Silver, self-wiping contacts
Light weight
High mechanical strength
Extra large “hooks” for easier “Loadbuster” tool engagement
High pressure contact back-up springs and convex spring washers
Operating eye with powerful mechanical “pry-out” action
Positive latching prohibits accidental opening
In-Line Disconnect switch (AIB)
A single phase, hookstick operated disconnect switch designed for in-line suspended applications. The “AIB” mechanically supports the full tension of the distribution line and provides high voltage insulation when open. When combined with a load break tool, it can be used to interrupt the full current load of the line on systems up to 34.5kV. A popular and economical solution to pole mounted switches, the “AIB” requires no additional support brackets and is ideally suited for armless construction. MindCore’s “AIB” is the only switch on the market with a design where mechanical connections do not simultaneously carry current

Mechanical connections do not simultaneously carry current
Fused In-line Hookstick Cutout Switch (CIF)
The “CIF” is developed to provide reliable overcurrent protection for primary distribution systems, safeguarding abnormal conditions such as line faults, line or equipment overloads, or equipment failure. Created for in-line suspended applications the “CIF’s” mounting arrangement mechanically supports the full tension of the distribution line. A popular and economical solution to pole mounted switches, the “CIF” requires no additional support brackets and is ideally suited for armless construction. When used in conjunction with a load break tool the “CIF” can be used to interrupt up to 200 without fuse blowing or arcing damage. The “CIF” may be used with any universal distribution fuse link.
PRODUCT FEATURES
High strength composite fibreglass tube
Copper current carrying parts
Impact resistant polymer insulator
Two piece expendable cap
Self locking hinges
High pressure contact back-up springs and convex spring washers
Operating eye with powerful mechanical “pry-out” action
Positive latching prohibits accidental opening
High impact shock absorbing backup spring
By-Pass Hookstick switch (CBP)
A compact, easily installed by-pass disconnect suitable for several applications. Ease of operation, safety of operating personnel,and its low cost are further advantages. The CBP provides a quickly operable line sectionalizing point with air gap insulation at each recloser or regulator installation. Break distance across the open gap of the by-pass switch is full value as compared to the 10 percent value supplied on the conventional regulator by-pass switch. No extra crossarms or special brackets are required for pole or crossarm mounting of the CBP.
PRODUCT FEATURES
Positive latching prohibits accidental opening
High presure contact backup springs
Operating eye with powerful mechanical pry-out action
Twin parallel copper blades
90 degree blade opening
NEMA terminal pads
Self wiping contact surfaces, hinge and jaw ends
Cycloaliphatic epoxy insulators
EXPULSION POWER FUSE (EPF)
A heavy duty power fuse offered in voltage ratings from 7.5 through 72.5 kV, in continuous ratings up to 400 A and interrupting capacities as high as 3 608 200 kVA symmetrical at 69 kV. This series of power fuses offers the maximum in reliability, ease of operation and economy. Reliability is assured by the dual operating characteristics of the expandable cap design and the arc quenching fuse element design. Ease of operation results from the drop out action of the fuse holder and the provisions for handling all ratings with a hook stick. Economy is significant at the time of the original installation and at the time of refusing. The cost of a fuse element is a fraction of the cost of refill units utilized by the competition with fuses of comparable performance.
