Purpose and Usage
　　 When the lighting arrester running the electric net appears deterioration, its power current will increase by and by until the system has a short circuit. Then grounding short circuit happens and makes a trip power cut accident. Even explosion may take place, threatening the safety of personals and equipments. The heat-broken dis-connector stops feasibility of lightning arrester explosion. Series of heat-broken dis-connector products of our enterprise can be used to protect vary types of distribution arresters of 6~10 kV. When deterioration takes place, the dis-connector disconnect the arrester before the relay protection. After acting, there are clear marks on the dis-connector to find the fault point and examine and repair. It needs non-maintenance, improving of the quality, stability and safety of the power system.
Service Condition:
1.Rated frequency of 48Hz ~ 62Hz.
2. Altitude is below 3,000 meters above sea level
3. Ambient temperature of -40℃~+50℃.
4. Outdoors available.

Technical Parameter
RBT series heat-broken dis-connector uses theory of heat break, when the fault current of the arrester going through the dis-connector gets up to a value, the heat energy in it detonates the special dynamite rapidly to disconnect to the ground while the disconnecting time decreases according the fault current. Each of the technical indicators of the product meets GB11032-2000 AC Oxide Surge Arrester Without Gaps（eqvIEC99-4）, JB/T8952-1999 Compound Coated Metal-oxide Surge Arrester Without Gaps for AC System Below 35 kV and IEEE.C62 Requirements of Distribution Lightning Arrester Dis-connector.
