Ningbo Zhengmao Electronics Co., Ltd
With convenient transportation and rapid economical development, Ningbo Zhengmao Electronics Co., Ltd. (with a former name Ningbo Shitong Telecommunication Component Factory) is located in the south of Ningbo Zhejiang Province, China. Founded in 2002, our company specializes in researching and manufacturing Switching Spark Gaps, Gas Discharge Tube and others.Switching Spark Gap (SSG) has a voltage mainly ranging from 110V to 800V with many advantages including complete varieties, good stability and long lifetime (it can be switched for over thousands of times to millions of times). This product is mainly used for ignition on HID ballast or street lamps, ect. Gas Discharge Tube is anti-aging with high insulation resistance, small capacitance and quick respond. It is widely used for over-voltage protection of telecom and other electronics as well as lightning protection.
We are a member under identification of Quality Management System (ISO9001-2008QMS). Our products all meet the International standard of IEC61643-311, Recommendation Standard of ITU-T K.12 and the national standard GB/T9043-2008/ Communication Equipment Over-voltage Protection with General Technical Conditions on Gas Discharge Tube, etc.. Gas Discharge Tube has got the TüV certification of German and SGS certification, meeting the rules of RoHS. Based on Quality, we aim at satisfying our customers by continually improving our product quality and service to meet your needs.
A: Our product is designed to withstand heavy use in industrial environments. The ignition frequency of the switching spark gap is at least 300000 times.
2. Q: What is your company's experience and reputation in the industry?
A: Our company has been in business for 22 years and has a reputation for delivering high-quality products and excellent customer service. We have worked with numerous clients in various industries.
3. Q: What is your company's policy on returns and refunds?
A: We have a flexible returns and refunds policy that allows customers to return products within 30 days of purchase for a full refund or exchange. We also offer warranties on our products to ensure customer satisfaction.
4. Q: Are there any certifications or standards that the product meets?
A: Yes, our product meets several industry certifications and standards, including TUV,ROHS,ISO,UL,SGS.
5. Q: How to maintain gas discharge tubes?
A: To ensure the normal operation and prolong the service life of gas discharge tubes, the following maintenance measures can be taken. Regularly check the condition of the gas discharge tube to ensure that it has not been physically damaged.Ensure that the working environment of the gas discharge tube meets its specified temperature range.Avoid exposing gas discharge tubes to excessive voltage to prevent permanent damage.
