Detailed Product Description

load isolation switch(switch,fuse isolation switch)

Absorbs the overseas advanced switch technology, uses modernized production craft, sharpened the switch line protection capability and the isolation performance greatly: The modulardesign structure, has the nimble diverse compositionality: The many kinds of opetation ods, has meet the customer different situation need.

Introduction

HGL series load ifolation switch(hereinafter called switch for short)is manfactured bu our company with the up-to-date thchnique imported from europe. This product meets the international thchnical level in the late 1990. Being the most ideal renewal of domestic congenetic products.

This kind of load isolation switch possesses flexible structure of modularized design. pssesses flexible and versatile compositionality, it adopts the shell made bu unsaturated po;yester resin reinforced bu flassfibre. It has vety high dielectric performance, protective capability, and reliable opetation.

The opetationg mechanism is an elastic-accunulationg accelerating mechanism for instant release, which makes instant on and of thedouble breakpoint contace. It has on relationship with the speed of opetation handle and increases greatly various electric properties ans mechnical properties.

Many forms of structers and opetations in which the on and off state of contact is observed through windows. There are opetations inside and outside the board. There are frontal and latetal opetations. There are connections behind the board.

This kind of switch has a good-looking outline and various functions, being very novel, simple and small-dimensioned, and the best choice among the congeneric priducts.

The HGL series product has acquired th 3C attestation certificate.

The series is conformity with standard IEC60947-3GB14048.3.

Characteristics of Products

1. The elastic-accumulating accelerrating mechanism for instant release realizesthe rapid making and breaking(13.8m/s),having no relationship with the speed of the operating handle, and increasing greatly the capability of extinguishing electric.

2. The shell made of unsaturatedpolyester resin reinforced by glass fibre pppppossesses excellent performance of flame resistane, dielectric performance, safe opetation, resist carbonic performance and resist impact performance.

3. Parallel double gap contact posssesses self cleaning functions.

4.All the contact materials are copper alloy plated with sliver, and possess two separation contact surfaces.

5. Large clearance of insulation.

6. Be on"o", the products can lock the handle with three locks at the same time and  can avoid error operation.

Product Usage

HGL series load isolation switch mainly suitable for AC50Hz,rated voltage to 660V,DC rated voltage up to 440V, rated current up to 3200A, the switch is used in the infrequent making and breaking circuit.

Operation Enviroment

HGL series load isolation switch can work relable under the following condition:

1. Height about level does not exceed 2.00m:

2. Ambiebt tempetature is not higher than 40^oC and not lower thatn -5^oC, relative humidity is not larger than 95%:

3. No explosive dangerous mediun environment:

4. No rain and snow attack environment.
