2. Touch the temperature of the socket to judge whether it is true or not. The fake "bull" socket has rough handle, poor temperature resistance and low flame retardant ability. Made of low-cost plastic, it is easy to soften and deform after long-term use, and it is easy to short-circuit and catch fire.
3. Look at the anti-counterfeiting logo to judge whether it is true or false.
Bull pioneered the socket button switch, which has won more than 90 national patents so far. In 2007, Bull, as the main proponent and drafter of the new national standard for power converters, proposed the combined hole standard with higher safety performance, which was not only recognized by relevant national institutions and authoritative experts, but also successfully listed as one of the new national standards for socket industry.
Extended data:
Three core technologies of bull socket;
1, anti-electric shock: the new national standard combined hole design, anti-electric shock shell structure design, socket safety design, safety insertion distance enhancement design and other multiple safety designs can effectively prevent electric shock accidents;
2, plug resistance: high-quality copper with patented sleeve design, strong elasticity, proper bite, not loose after 5000 plugs, which can effectively prevent arc discharge.
3. Flameproof: interior materials is made of all flame-retardant engineering materials, which will not burn at 750 degrees, effectively preventing fire and eliminating potential safety hazards.
