![]() | Polymeric and Polymeric Housing Surge Arrester19 visitsClassification of surge arresters: Distribution arresters: The distribution arresters are used for the protection of equipment such as distribution transformer, switch cabinet, box type transformer, cable terminal and less-oil pole switch against damage from atmospheric over-voltage and switching over-voltage. Station arresters: The station arresters are used for protecting A. C electrical equipment or power plant and substation against damage from the atmospheric over-voltage and the swithching over-voltage. Transmission line arresters: The transmission line surge arresters are the major protective apparatus used for preventing transmission line from being struck by lightning. |

![]() | Fiberglass/Vulcanized Fiber Combination Tube17 visitsCombination tube is made by overwrapping vulcanized fiber tube with epoxy resin saturated fiberglass filaments. The angle of filament winding is usually set at 55. Vulcanized fiber tube becomes an integral tube liner which provides gas-generating and arc-quenching characteristics. Epoxy resin saturated fiberglass provides strength and water resistance. The combination tube is usually coated with UV resistant paint in gray color. Fiberglass/vulcanized fiber combination tube has the following advantages over fiberglass/polymeric synthetics combination tube: No-spark generating, char layer forming to prevent liner from excessive ablation, and the optimum amount of arc-quenching gas generating. The main application of fiberglass/vulcanized fiber combination tube is used in expulsion fuse tube cutout for interrupting high voltage AC circuits during power surge. |

![]() | LP220V-**K Series Lightning Protector for Power Supply19 visitsLP220V-**K Series Lightning Protector for Power Supply Brief At present the latest model of the protection of power supply L-N,L-PE,N-PE dedicated ccmodule from my company successfully into the market, is currently the highest-the ratio of price and performance lightningproof module. Other types of lightningproof module provide only common model protection, such as when lightning strikes occur ,the module may cause damage. According to the Leidianfanghu power available to the urgent need, we developed a novel lightningproof modular for power supply, it belongs to the intellective device, and provides better protection for power supply, electromagnetic compatibility characteristics also higher. It has a delicate frames, thermal disengagement button set within,technologically-advanced, user-friendly, economical and practical, protective functions strong, broad scope of application, with independent intellectual property rights. It used to the entire protective circuit and "3+1" circuit, applies particularly to lightningproof protection for the power supply of CATV amplifier. Principles in the normal work situation, the lightningproof component within lightning arrester is in the high impedance state. When unexpected over-voltage, over current and thunderbolt occurs, lightningproof component will switch on rapidly, and over-voltage, over-current and thunderbolt invasion wave will be limited to the permitted extent for electricity equipment, thereby protects the power supply to run normally. The Lightning protector also has the failure instruction function: After failure the red LED is bright, indicated the Lightning Protector failed, should give the replacement. Parameter Model Max discharge current 8/20?s(kA) LP220V- 5K 5 LP220V-10K 10 LP220V-15K 15 LP220V-20K 20 LP220V-30K 30 Voltage (ACV): 220,protection voltage(DCV): 660+/-20%,stop fire class: 94V-0,size (mm): 52.5*40*15,down-lead: AVR0.75, Working condition: temp.-30~70, r.h.max95(%),a.p.70~106(kPa). Applications the series lightning arrester module applies to switching power supply,industrial protective module control, communications, cable networks, and other fields, such as, electrical control cabinets, monitoring equipment, solar power generation equipment, wind power equipment, industrial control, instrumentation, computer peripherals. |
