DIN46228 regulations for insulated protective caps
The function of the insulated toe caps The purpose of protection is to prevent the conductor wire from being spliced and to protect the individual strands against mechanical forces. Protective ferrules offer many electrical and mechanical advantages in electrical engineering systems and it is important that there is a good connection between the insulated ferrules and the copper conductor when using a terminal block.
To establish a secure connection, it is essential to have a good crimping tool and quality terminals or ferrules.
Although we establish that both the crimping or crimping tool is of quality, the insulated toe caps They must also meet a minimum standard.
In Europe, the influence of consumption of electrical connection materials such as protective caps of Asian origin has spread, as is happening in Taiwan. Some of these manufacturers try to comply with the regulations of the countries to which they export, but it is very common to find faults in the connections. It is for this reason that the main players in the European market in the production of crimping tools realized that the level of connection established by their products with protective ferrules left much to be desired. Many European companies carried out a plan to establish new quality values for manufacturers of insulated protective caps, by updating the DIN standard.
DIN is an acronym for German Regulatory Institute “Deutsches Institut für Normung” and they currently have more than 70 committees and departments that are responsible for reviewing and improving product standards in the EU. The DIN46228 standard for protective toe caps was originally published in September 1990 and in March 2020 the new DIN46228 standard came into force for toe caps of protection isolated, from 0.5mm to 50mm in diameter.
The regulations keep intact aspects such as the color configuration according to the diameter and length of the insulated toe or the minimum cumulative tension force (estimated at 250 N/mm2). The differential adjustment is found in the voltage increase now allowed up to 105 volts and the new parameters to test the material and certify its compliance.
Our insulated protective toe caps
The protective toe caps that we supply at Fleximat are produced in the European Union, specifically in Germany. We comply with the new DIN regulations for protective terminals and ensure absolute quality.
The interior of the tips is made of copper and then a Zinc bath is applied, which promotes greater conductivity and durability and the minimum bath that we offer in all our tips is 3 microns.
The insulated toe caps They come covered in polypropylene (PP), which offers high resistance to chemical agents and ensures the toe cap up to 115°.
In addition, we have several of the most demanding and prestigious certifications at an international level, which guarantee the quality of the product and open the doors to export to other countries.
Some of our most notable certifications for electrical protection caps are:
- UL Certification: Regulations for the US market
- CSA Certification: Regulations for the Canadian market
- CE Certification: Regulations for the European market
- RoHS Directive Declarative Certification
