In addition to the function as a fuse used in power distribution system the SSOC(NCF) 3 fuse can be also applied as the outdoor load switch equipped with an independent arcing chute for loadbreak which restricts the electrical arc and provides de-dissociation function.

Pulling the hook of fuse with rod the operation for loadbreak is carried out. The load breaking feature will prolong the fuse’s service life. According to the principle of independent loadbreak the load current can be interupted safely and easily with ordinary rod.

DNK have the most innovative technology in the international. We will provide the excellent service and favorable price for you!

2. Standard

The design and test of SSOC(NCF) fuse accords with requirements of the following standards:

 IEC282.1                                                 IEC787

ANSI C37.41-94                                     ANSI C37.42-94

GB 15166.3-2008                                    GB 311.1-97

DL/T 640-97                                            DL/T 593-96

3. Product feature

1. Precise and reasonable integral structure---presents stable matching of all parts, flexible operating and provides the power line with reliable operation and manipulation with convenience.

2. All conductive parts are made of conductive pure copper, high elastic conductive copper alloys and processed with over 0.3mm silver-coating which improved the erosion resistance, reduce the contact resistance and temperature effect and increase the conductive performance.

3. Ultraviolet resistant and waterproof fuse tube---presents wet-proof, undeformed, long service life and high strength. With the structure of exhausting gradually gas of two-end the fuse tube enhances the breaking capability of short-circuit current and breaks high and low short-circuit currents.

4. Anti-bird insulator---applying the superior insulating matrial of electrical porcelain, large creepage-distance and suitable for different environments, the design of structure is optimized for preventing efficiently the insulator from touching bird.

5. beryllium bronze conducting plate---presents strong mechanical elasticity, no spark while switching off and improves evidently the conducting capacity, contact stability and reliability of the fuse.

6. Upper and lower copper supports---ensuring operation without shaking, rebounding or separating.

7. High strength cast copper silver-plated trunnion and cast copper trunnion mortar---strong strength, precise matching, flexible operation, overcome the problem of swing of the fuse tube when switching on.

8. Parallel groove connecting terminal---provides simple and reliable connection
