Design & Specifications

Vrupt7

2. Stainless steel hook

For loadbreak tools like the LoadBuster

3. Expansion cap

Especially design to relief the pressure

Easily replaceable

High Strength U''V'' resistant fuse tube

Designed to handle the pressure

Positive lever operated latch prevents opening from vibration or violent impact to the pole or the use of cover-up equipment

4. Upper support

Copper alloy - have extra thermal capacity and contact area for dependable, continuous operation at the disconnect rating. Their large, heat absorbing mass conducts the highest rated momentary currents without overheating.

5. Fuse holder contact

Ensures complete closure while minimizing electric arc The connection between shoe and terminal forms a reverse current loop, which further increases contact pressure during high current faults and prevents pitting and burning

6. Linkbreak

Patented mechanism for ensuring fuse breaking

1. Connection terminals

Enhanced – allowing cable connection vertically or horizontally

Lift ring specially designed to facilitate the handling and installation of the fuse holder

7. Fuse terminal straight through arrangement

Eliminates difficulty of winding and securing cable

Remove the stress on the fuse link and prevent change in its characteristics

Batôn

This innovative component is the key to the VRupt7's exceptional performance and safety. The VRupt7 baton is engineered with a size of 484.7 mm in length and a radius of 25.4 mm on the outside and 12.7 mm on the inside. This robust design provides a sturdy foundation for the fuse and ensures a secure connection between the upper and lower contacts when the circuit is closed.

​

Crafted from fiberglass, the baton's filament-wound tubing incorporates an arc-extinguishing liner for enhanced safety. The casting parts are made of a copper alloy, adding to the baton's durability and conductivity. One of the standout features of the VRupt7 baton is the Linkbreak mechanism. This ingenious design allows a lineman to manually break the fuse link within the baton, isolating the current and preventing any accidents or damage to nearby electrical cables.

 

This safety-focused innovation is a true game-changer, making the VRupt7 the easiest and safest fused cutout to operate.

​

The VRupt7 baton exemplifies CO7 Technologies' commitment to engineering products that prioritize safety, reliability, and ease of use for our customers and the linemen who work with our equipment.

Linkbreak Attachment

The Linkbreak mecanism is designed so that it will break element of fuse links rated from 1/3 through 100 A with a minimum of effort. Fuseholder extinguishes load current as if fuse element had melted due to an overload condition.

​​

  • Low initial cost compared to cutouts with integral loadbreak devices;

  • ​No complicated interrupter device to possibly fail;

  • Can be hookstick operated from ground with standard or extend stick. It is not necessary to climb the pole as it is for portable loadbreak tool in the event bucket truck is not available or location is such that it cannot be reached by bucket truck.

Advantages

General

  • The circuit-breaker has a service life of 30 years in the extreme conditions of Quebec (temperature, humidity, salty air).

  •  The circuit-breaker's robustness and versatility enable it to be used in a wide range of applications, such as protection of transformers and capacitive networks. Transformers and capacitive networks

  • Robustness reduces false opening and minimizes maintenance and operator travel costs

  • A single model can be used across an entire electrical network, maximizing inventory management

​

Operational safety

  • Eyelet design facilitates fuse insertion on the base, especially when using long ground poles

  • Unique locking system ensures the fuse holder closes securely, ensuring the safety of line workers

  • Gripping hook design and position enables reliable use of LoadBuster for fuse opening

  • The expansion plug allows pressure to escape upwards in the event of a short-circuit, minimizing the risk of fire and protecting operators

  • The unique fuse attachment system prevents the fuse from elongating, thus reducing its breaking capacity. It also minimizes the need for operators to travel for maintenance

  • The "linkbreak" allows a lineman to manually break the fuse inside the tube. Although this destroys the fuse it allows the circuit-breaker to be opened, now de-energized, without the use of special tools, and will not create a dangerous arc. The design of the breaking mechanism provides a reliable break that no competitor can offer.
