Electric heating and electrical: heating elements such as electric heating films or carbon fiber generate heat
Based on the "Electric Heating and Electrical II" you entered, this likely refers to a specific enterprise. Combined with your location in Yangzhou City, Jiangsu Province, and relevant business information, the best match is Lanzhou Electric Heating Appliance Factory No. 2.
The following is detailed information about this enterprise, along with industry background and safety knowledge related to "electric heating and electrical."
1. Enterprise Entity: Lanzhou Electric Heating Appliance Factory No. 2
This is a small and micro enterprise located in Lanzhou City, Gansu Province, whose predecessor was a collectively owned enterprise.
Full Name: Lanzhou Electric Heating Appliance Factory No. 2
Established: June 30, 1984
Legal Representative: Kang Yongqing
Registered Address: No. 191 Langongping, Qilihe District, Lanzhou City, Gansu Province
Business Scope: Mainly includes sales of radiators, electric cookware, transformers, and switch cabinets.
Related Investments: The enterprise has invested in "Lanzhou Xijinyuan Property Management Co., Ltd." (100% shareholding) and "Gansu Sanyuan Food Co., Ltd." (revoked).
2. Industry Concept: Electric Heating Appliances
If you are not specifically referring to the above company, but want to understand the technical field of "electric heating and electrical," it refers to devices that use the thermal effect of electric current (Joule's law) to convert electrical energy into heat energy.
Core Principle: Current passes through heating elements such as resistance wires, electric heating films, or carbon fiber to generate heat.
Common Products:
Civilian: Electric heaters, electric blankets, electric water heaters, electric heating clothing (the recently popular "wearable electric blanket").
Industrial: Electric boilers, industrial ovens, liquid heating equipment, etc.
Development Trends: Currently moving towards intelligence (remote control via mobile phones, AI temperature control), energy efficiency (carbon fiber materials, frequency conversion technology), and customization.
3. Safety Tips: Usage Standards for Electric Heating Equipment
Electric heating equipment typically has high power and directly generates high temperatures, so safety must be emphasized during use. Based on the latest tips from the Ministry of Emergency Management and news reports, please note the following:
Look for "3C" Certification: When purchasing products such as electric heaters and electric blankets, ensure they have the national compulsory certification (3C) mark, and reject "three-no" products.
Prevent Fire Risks:
Keep away from flammable materials: Do not pile clothing, curtains, or other flammable items within 1 meter around electric heaters.
No covering: It is strictly forbidden to cover electric heaters with clothing for drying, as this can easily cause heat accumulation and lead to fire.
Avoid folding: Flexible heating devices such as electric blankets and electric heating clothing must not be folded while powered on, as this can cause internal heating wires to break or local overheating.
Do not exceed service life: The safe service life of electric blankets is usually 6 years; exceeding this can lead to aging of wires, damage to insulation layers, and short circuits.
Standard electricity use: High-power electric heating equipment (such as electric boilers and electric heaters) should use dedicated sockets, avoiding sharing a power strip with other high-power appliances to prevent overload.
If you are looking for similar enterprises in Yangzhou, Yangzhou (especially Baoying County) is a famous "hometown of electric heating appliances," with many manufacturers producing heating cables, mica heaters, and ceramic heaters (such as Yangzhou Enyuan Electric mentioned earlier). If you need to find local suppliers in Yangzhou, it is recommended to search directly for "Yangzhou Electric Heating Appliance Factory" or "Baoying Electric Heater."

Lightning Counter Calibration Tester
The lightning counter calibration tester, also known as a lightning counter tester, is a specialized portable device used in power systems to check whether the discharge counter of a lightning arrester can operate normally. It simulates lightning impulses to verify whether the counter can accurately record the number of lightning strikes, making it an important tool for ensuring the safe operation of the power grid.
⚡ Working Principle
The core principle of the calibration tester is to simulate a standard lightning impulse wave. Internally, it uses a capacitor charge-discharge circuit to generate a transient high current (such as 100A or higher) that conforms to a standard (usually 8/20μs waveform) and applies it to the counter under test. If the counter functions normally, its count value will increase just as if it had experienced a real lightning strike.
