This Thai standard three pole elbow power plug is strictly manufactured in accordance with the Thai TIS 166-2549 standard and is suitable for 220V/50Hz civilian power supply systems in Thailand and some Southeast Asian regions. It is a power connection accessory specifically designed for electrical appliances with a metal shell, and combines grounding safety protection, elbow space saving structure, and stable electrical output. It is widely used in various household and commercial high-power equipment and is also a standard Power cord component for exporting electrical appliances to the Southeast Asian market.

The plug adopts a classic three cylinder pin triangle layout structure, and the size and inter pole distance of the three metal cylinder pins all comply with Thai official specifications. It can be used for all compliant Thai standard wall sockets, sockets, and extension cords on the market, without any compatibility problems such as loose insertion or misalignment. The independent pin in the middle is the grounding electrode, which is longer than the neutral pins on both sides, realizing the safety logic of grounding first, then powering on, power-off, and finally disconnecting from grounding. When metal shell equipment such as refrigerators, washing machines, and electric water heaters experience leakage faults, the grounding pin can quickly dissipate the leakage current, avoiding electric shock caused by human contact with the shell and greatly improving the safety of high-power electrical appliances. The root of the pin is equipped with a black insulation sheath, which can cover the live metal parts even if the plug is partially pulled out during the insertion and extraction process, reducing the risk of accidental contact and electric shock.

The product adopts an L-shaped elbow integrated design, which is the prominent practical advantage of this plug. The traditional straight head plug protrudes significantly outward when inserted into a socket, occupying a small space behind cabinets and appliances. The elbow outlet structure allows cables to extend parallel to the wall, greatly reducing the depth of the plug's occupation and perfectly adapting to narrow wiring scenarios such as cabinets, TV backs, and equipment cabinets. At the same time, it avoids long-term hard bending of wires, reduces core breakage and outer skin cracking problems. The tail of the plug is designed with multiple wave shaped buffer wire sleeves, and the multi-layer wrinkled structure disperses the stress generated by pulling and bending. When moving electrical appliances or storing wires in daily life, it can effectively protect the root of the wire and extend the service life of the entire power cord. The overall shell is injection molded, with strong seamless sealing, which can prevent dust and water vapor from entering the internal conductive area, reducing the probability of short circuit and metal oxidation.

The conductive pins are made of high-purity copper material stamped and formed, with nickel plating on the surface for oxidation resistance, low conductivity loss, and controllable temperature rise during long-term full load operation. There will be no faults such as plug heating, sparking, blackening, or oxidation. After thousands of insertion and extraction tests, they still bite tightly and will not have loose connections. The plug housing is made of V0 grade flame-retardant insulating plastic, which is resistant to high and low temperatures, impact, and can quickly extinguish itself in the presence of an open flame. It completely isolates the internal charged metal parts and avoids the hazards of electric shock and fire from a physical perspective. The plug is equipped with a strong locking buckle inside, and the cable is firmly crimped. Through standard tensile testing, it is not easy for the wire core to fall off or have poor contact during daily dragging. The supporting power cord is made of multiple stranded oxygen free copper conductors, with stable current carrying capacity. The outer PVC insulation sheath is flexible and wear-resistant, suitable for long-term indoor wiring use.
