Metal Oxide surge arresters Cable protective layer protection


35KV large cross-section power cables and the power cables of 66KV. 110KV voltage class and above is single-core cable. One side of the cable security layer is three phase interconnection and grounding, and the other side is nongrounded. when lightning stroke or inner over-voltage wave is flowing along the cable core, the cable metal protection level ‘s nongrounded side will appear bigger impulse over-voltage When the system short circuit fault, the electricity is flowing the cable core, and the security layer nongrounded side will appear the bigger power frequency induction over-voltage. The above over-voltage may puncture the insulation of cable outside protection level, bring about the multipoint earthing faults of the cable metal protection level, it will largely influence power cable's normal operation even sharply reduce the cable service life. Therefore, electric power industry standard DUT401-1991 <High Voltage Power Cables Choose Guideline > provide: Must use cable security layer protector to limit the power cable metal shielding layer's (or metal sheath) induced voltage and fault over-voltage.



According to the cable line of one side grounding and cross-bonding, the silicone rubber cable security layer protector we design has the feature as below


1. ZnO varistor, large discharge capacity, less residual, high protection ratio

2. The biggest to restrict and reduce the power frequency induced over-voltage and impulse overvoltage of the cable line metal security layer.

3. The silicone rubber housing is overall moulding press, good sealing, strong anti-fouling ability, light weight, small size, prevent collision, prevent heat, prevent cold, ageing resistance and no maintenance.

4. If it is with the discharge counter or lightning monitor, it will automatic accurately record the action number and operating quality under different over-voltage.
