1. Summary

With the rapid development of computer technology, transducer technology, and network

communication, the power system network has advanced requirements. As a result, using primary equipment with single functionality has become inconvenient. To address this issue, it is necessary to develop intelligent integration switches based on terminals for the entire power system. Our

company has developed the SFE Series, an intelligent integration outdoor AC high voltage vacuum circuit recloser, which is an upgrade from outdoor vacuum circuit breakers. Our reclosers comply with relevant standards, making them a reliable choice.

3. Before using reminding

To ensure the highest level of quality and performance, the SFE Series switch undergoes thorough factory adjustment and sealing. Additionally, we provide a cable connector assembly that allows for easy interconnection of wiring to the SFE switch. For added flexibility, we also offer optional accessories such as potential transformers or surge arresters that can be supplied with the switch.

4. Transport, Lifting, flitting notice

4.1 Lifting of packing case

4.2 Transport

During transportation, the SFE circuit breaker is securely packed in a seaworthy manner and

positioned in the "OPEN" state. The circuit breaker is usually packed in one case with the

electronic control cabinet, while the steel support fittings and other accessories are packed in a separate case. The following documents are also included with the SFE breaker: instruction

manual, factory test certificates, drawings, and a packing list.

It is important to transport the circuit breakers only in their packed condition, taking necessary precautions to ensure safe and damage-free transportation.

. Ensure that packing cases are not placed on wet surfaces / waterlogged areas.

. Breakers should not be stacked one over the other.

4.3 Receipt & Storage prior to installation

Store the breaker indoors with complete packing to protect it from direct sunlight, rain, or snow.

The breaker can be stored for up to 3 months from the date of shipment from the factory. For longer storage, remove the packing and store the breaker in a controlled environment with a leakproof roof, solid and flat ground, relative humidity below 50%, and temperature of 20°C (±10°C).

4.4 Lifting of SFE circuit breaker

Note:

Very dangerous! Don’t allow to give much force on the bushing current transformer side.

5. S F E type Circuit Breaker unit installation on pole

Different sizes of mounting bracket

The weight of SFE12 circuit breaker =92kg. SFE15&GTE27=137kg.

SFE27H&SFE38 circuit breaker weight=300Fg.

6. GTK type Electronic controller installation on pole

GTK type electronic controller weight=20kg

Note:

The controller mounting bracket is provided by end-user. Above installation

Dimension for clients make controller’s mounting bracket using.

7. Interconnect with circuit breaker and electronic controller
