Shanxi Province Bureau of Quality Supervision released the second quarter of provincial quality supervision and spot checks showed that : four batches of food processing, electrical appliances and 12 batches of wire and cable is apt to electric shock , leakage accidents quality.
First, excessive heating project , could easily lead to motor overheating caused by fire and electric shock. Fever is the main reason for the project exceeded the optional motor load is low , technical structure is irrational, leading to cooling problems , fever, excessive . Second, the external power cord connection and failed , to save the cost of individual enterprises , the use of the power cord cross-sectional area is smaller , not meet standards. Overload the use of such products will make a long line of body heat , insulation aging resulting in leakage or fire cracking accident ; as thin wire , by external force in the post , easily lead to broken power lines , plus individual product nor power Cable clamping device, by external forces , the power cord is pulled off , could easily lead to short-circuit power lines , leaving the security risk. Third, protection against electric shock, failure , food processing equipment often requires the use of hand contact with operations, inadequate protection if the live parts , it is prone to risk of electric shock .
The total of the city and Datong , Yangquan market distribution of the 20 batches of wire and cable for the supervision of sampling , 12 batches failed , the city market in which there are six batches . Failure mainly conductor resistance , insulation (or sheath ) tensile strength before aging . Conductor resistance directly reflects the copper used in wire and cable ( aluminum ) material good or bad or whether the actual cross-sectional area standards , exceeding the wire and cable conductor resistance in use easy to over- heating the wires caused a fire accident . The low tensile strength of insulation wire and cable , insulators in the use of manipulation to rapidly aging , embrittlement and loss , resulting in exposed conductors , can easily lead to leakage accidents , endangering personal safety. Main reasons for failure of some manufacturers do not follow the national standards organization of production ; some one-sided pursuit of business efficiency , reduce production costs for the shoddy , jerry-building
In addition, the quality supervision departments also conducted a gas cooker and cement random inspection . 20 batches had failed to pass a gas cooker batch . In the kitchen by the Taiyuan Municipal Department of the new distribution of the labeled Tat Distribution Letter Wo Electric Co., Ltd. , Zhongshan City, Sakata produced cards JZY-XHF33 type gas cookstove, the thermal load deviation , the main fire, heat load measured conversion does not meet standards. 27 batches of cement in eight batches of substandard products , the main problem is that strength does not meet quality standards .
