Refractory shielded cables will play an irreplaceable role both now and in the future. It plays an irreplaceable role in safeguarding people's lives and property.

Due to the large population of our country and the high density of personnel in public places, 80% of the deaths in public places are caused by the inhalation of toxic combustion gases. The large amount of smoke generated during combustion is also detrimental to the evacuation of personnel. The 9/11 incident that shocked the world fully illustrates the role of fire-resistant cables. When the fire source burns the fire-resistant cable, the cable will not be affected for a certain period of time and will work normally. Generally, a large amount of harmful gas is generated after the fire of the cable. In the event of many fires, 90% of the victims die from inhaling harmful gases, but not from the source of the fire. The fire-resistant cable uses low-smoke, halogen-free materials, giving people more time to escape.
Langfang Yaqi Cable Co., Ltd. considers the safety of people's lives and property every year to invest more than 1 million yuan in innovation and research on this project. And the staff will go abroad for research and study to improve the quality of the company's products. Fire is inevitable, but we give people the security they need. Minimize the loss of property.
