As an electrical product, LED lamp holders naturally need to have cables connected inside. For product safety, corresponding wiring standards are required. Below, professional manufacturers will introduce us to the internal wiring standards of LED lamp holders. Come on Check it out.

LED lamp caps are required by the specifications. The internal wiring of LED lamp caps needs to be checked in four areas: wire diameter and insulation thickness, mechanical damage, insulation layer heating temperature, and whether the insulation meets the requirements. Generally speaking, there will be no problems with the internal wiring in the protection of mechanical damage, and the main problems will lie in the other three aspects.

According to the requirements of GB7000.1, when the normal current of the positive bayonet lamp holder is less than 2A (the operating current of general LED fluorescent lamps will not exceed 2A), the nominal cross-sectional area of the internal wire is not less than 0.4mm2, and the thickness of the insulation layer is not less than 0.5mm . In addition, from the perspective of insulation, since the aluminum shell is a touchable metal part, the basic internal insulation cannot directly touch the aluminum shell. This requires the internal wire to be a double insulated wire, unless there is a relevant certificate that can prove that the insulation layer of the wire can meet the reinforcement. Insulation requirements, at this time, it is also possible to use single-layer insulated wires for internal wires. However, the internal wires used by LED fluorescent lamps on the market rarely take into account the requirements of cross-sectional area, insulation thickness and insulation wire level at the same time.

In addition, when the internal wires of the LED lamp holder are routed, attention should be paid to prevent the wires from directly touching the parts that heat the internal power supply, such as transformers, filter inductors, bridge stacks, heat sinks, etc., because these components are used during the operation of the LED lamp holder. , The temperature is likely to exceed the heat-resistant temperature value of the internal wire insulation material. When the internal wires are routed, do not touch the parts that generate a lot of heat, which can prevent the insulation layer from being damaged due to local overheating of the insulation layer, causing safety problems such as leakage or short circuit.

　　The wiring standards for LED lamp holders are the above, only regular manufacturers will strictly implement them, and the product quality can be guaranteed. If you want to purchase reliable LED lamp cap products, please feel free to inquire our company, we will definitely be able to give you a satisfactory answer.
