A bright moon overhead, a home filled with joyful laughter.

As the nation celebrates together, don't let voltage fluctuations "sneak attack" your home!

The choice of housing material in electrical product design directly impacts the product's safety, durability, appearance, and cost control. Different plastic materials possess distinct characteristics, making them suitable for various usage environments and functional requirements. This article provides a detailed analysis of six commonly used engineering plastics—PA, PC, ABS, PP, PVC, and PET—focusing on their advantages, disadvantages, and suitable applications in housing design.

This article explores the core knowledge of these devices, specifically fridge guard and TV guard units, to help you scientifically safeguard your home's electrical system.

The core mission of a Surge Protective Device (SPD) is to neutralize voltage and current surges that far exceed normal levels within microseconds or even nanoseconds. Today, we will take you deep inside an SPD to see how components with different characteristics work together in precise coordination to complete this ultra-fast protection.

For over 19 years, Wenzhou BXST Co., Ltd. has been a trusted manufacturer of voltage protection products. We proudly present the V309 and V310 Voltage Protectors—designed to safeguard your home appliances against unexpected voltage surges and fluctuations. Featuring flame-retardant housings and a wide voltage range (90V–140V), both models offer automatic power cutoff during abnormal conditions. With easy plug-and-use operation and support for devices up to 1800W, they provide essential protection for refrigerators, TVs, washers, and more.

As a precision appliance operating, household refrigerators have significantly higher voltage stability requirements than ordinary household appliances. Although standard household voltage ranges from 110V to 240V, when voltage fluctuations exceed the ±10% threshold, the compressor motor may experience insufficient torque or overload operation leading to winding overheating, while electronic control systems may suffer program malfunctions. Laboratory data indicates that voltage abnormalities can reduce refrigerator lifespan by over 40%.
