CITEL生产的浪涌保护器可广泛地运用于交流、直流电源、电话、数据及射频同轴线路的防护。 我们的产品设计特别针对无线宽带、电信、自控仪表、太阳能光电、军事安全等产业的特殊性，提供了专业有效的过电压保护。
       CITEL 浪涌保护器是PBXs (交换机)、电信设备、无线电基站、全球定位系统、无线系统、配电控板和移动 通信基站抵御雷电浪涌和瞬时过电压的理想选择。我们的产品为基于高敏感微处理器的电子设备，如PLCs, MUXs, HUBs, RTUs, SCADA, THCs, 及遥感勘测系统，提供了强大保护功 能。
       我们很多保护模块可用于4-20 mA电流环路，RS232，RS422, RS423, RS485, T1, E1, ISDN，56K, DDS，数 据专线，电话线路，电源线路，以及同轴线路和双绞线路. 这些模块可通过标准DIN导轨或安装面板连接到被保护设备上，有的可以直接通过 插头连接。输入输出端可以通过螺丝接 线柱，DB9, DB15, DB25接头, 或RJ11, RJ45插孔连接。CITEL同轴防雷器的接头种类齐全，有N头, BNC头, TNC头, SMA头, 7/16头，F头等。
       CITEL大部分产品采用了先进的高可靠性多级保护设计，响应速度快，耐冲击容量高。这些特点延长了被保 护设备的使用寿命，大大降低了停机产生的损失。CITEL浪涌保护器每次工作后会恢复到原始状态，不需日常维护。在浪涌电流过大的情况下 ，浪涌保护器会短路失效，确保您的设备完好无损。
       此外， CITEL也是全球著名的气体放电管生产商。我们的产品种类多样，可满足直流导通电压75V到2500V 的不同选择，并可满足表面贴装和透孔安装的使用条件。
       CITEL放电管绝大多数型号都通过了UL,CSA,CE和VDE认证。

First Gas Discharge Tube (GDT) in 1944 – 60 years in surge protection;
One of the largest GDT manufacturer in the world, 30 million per year;
Full range of products for surge protection:
　　Gas Discharge Tube (GDT);
　　AC surge protection modules;
　　AC surge protection panels;
　　Data and telecom surge protection device;
　　Surge Protection device for coaxial transmission.
CITEL manufactures a complete line of surge protectors for AC power, DC power, telephone, data and RF coaxial lines. CITEL surge suppressors have been especially designed to provide an effective solution to Broadband Wireless, Telecom, Automation Control Instrumentation, Solar Photovoltaic, Military and Security Market industries.
CITEL surge protection devices are ideal to protect PBXs, Telecom equipment, Radio Base Stations, GPS, Wireless systems, Power Distribution Panel Boards and Cellular Sites against lightning surges and electrical transients. They provide rugged transient protection for very sensitive microprocessor based equipment such as PLCs, MUXs HUBs, RTUs, SCADA, THCs and Telemetry systems.
Many models are available for 4-20 mA current loops, RS232, RS422, RS423, RS485, T1, E1, ISDN, 56k, DDS, leased lines, telephone lines, RTD, power supplies as well as coaxial cable and twisted pairs. They are available in DIN rail mount, panel mount or directly plug-in to the equipment to be protected. I/O connections can be made either via screw terminals or DB9, DB15, DB25 connectors or RJ11, RJ45 jacks. CITEL's coaxial lightning surge arrestors feature also all types of connectors such as N, BNC, TNC, SMA, 7/16 DIN and F type.
Most of CITEL surge protectors use a state of the art, heavy-duty, multistage design that combines a fast response time and high power handling surge capability. They will ensure an increased life expectancy for your equipment and will eliminate costly equipment downtime. CITEL surge suppressors automatically reset after each surge and are maintenance free. Under the most severe conditions, the surge protector will fail short leaving your equipment fully protected.
In addition, CITEL is a worldwide leader manufacturer of surge arrestor gas tubes and provides a complete line of gas discharge tube components from 75V to 2500V available for surface mount and through hole mounting. Most CITEL surge suppressors have been approved by all major international organizations like UL, CSA, CE, VDE.

Citel is one of the pioneer companies who introduced concept and state-of-the-art technology of surge protection into China. Seeing the growing potential Chinese market, and to serve the Chinese customer closely and professionally, Citel Group established its subsidiary in China– Shanghai Citel Electronics Co., Ltd. in 1996. Since then, Citel has acquired substantial market shares and become a widely recognized brand on the market.
