The TruSeal range is made from the highest quality materials, with silicone seals in both the polyamide and nickel-plated brass cable glands, to suit the arduous conditions that our products often face. TruSeal Polymer comes with a UL94 V-O option suitable for the harshest of flame retardant, low smoke and fume zero halogen applications.
该范围符合哪些标准?
CMP Products leads the way in compliance with technical standards, and with a dedicated certification team, we design, manufacture and supply products that are compliant with all of the latest standards for IEC, NEC and CEC based installations.
In order to ensure that the TruSeal cable gland range is ‘fit for purpose’, CMP Products ensures that the full range is tested and often certified to the most onerous cable gland market standards. In this case that is IEC or EN 62444 (formerly EN 50262).
What Explosive Atmosphere Certification does the Range Hold?
CMP Products remains in constant touch with the changes in development of national and international technical standards, and consequently is able to offer product solutions that are certified for multiple global applications.
Certification to IEC / EN 60079
The TruSeal range has been certified in accordance with IEC / EN 60079 parts 0 (general requirements), 7 (Ex e increased safety) and 31 (Ex t dust ignition). The means that this product range is safe, and certified to use in Explosive Atmospheres with Ex ‘e’ equipment and will maintain the integrity of the installation. Below shows the minimum requirements that a product needs to meet to be safely used for an Ex ‘e’ application.
该范围的密封方法是什么?
CMP有利于位移密封方法,其中密封件在来自尼龙指的压力下逐渐压缩,并且沿着电缆的长度轻轻地移位,直到它具有有效的密封。该方法提供了卓越的控制密封环到电缆的压力。
TruSeal products are available with three different circular seals (as well as additional options for
non-round cables) to suit the customers’ needs, these seals boast the widest cable sealing range on the market for an equivalent cable gland. Having such a wide sealing range means that the customer would be able to buy fewer different sizes of cable gland for a particular project, reducing overall cost. An additional benefit of a wide sealing range is that often, for a specified cable, CMP will be able to offer a smaller cable gland than their competitors.
可用的线程选项?
TRUSERAL电缆腺可提供标准或长型公制线以及NPT。由于外壳壁厚或由于附件的积累,长线在安装中通常是至关重要的。
所有NPT线程都符合NPT线程规范ANSI / ASME B1.20.1,可用于专门设计的入口螺纹密封垫圈,用于与非线性条目一起使用。
What is the IP Rating of The Range?
全部products within the TruSeal range are tested to IP66, 67, 68 and 69K; the details of the testing and the level of protection provided is shown in the tables opposite. To ensure that these ratings are achieved, CMP products provides ‘O’ ring face seals for metallic products and entry thread polymer seals for the plastic glands as standard. These ensure that no matter what the product thread, enclosure material or surface finish, the required environmental protection will be achieved.
What Materials are Used for TruSeal?
我们仅使用最优质的材料来满足我们产品经常面临的艰苦条件。对于特动范围,这包括用于密封件的电缆腺和硅氧烷的聚酰胺或镀镍黄铜。
What accessories are available to use with TruSeal?
Locknuts
CMP polyamide and nickel plated brass locknuts have been specifically designed for the TruSeal range to secure your cable gland into non-threaded enclosures. Cable glands can be bought with or without locknuts depending on your specific needs and are available with metric or NPT threads.
入口螺纹密封
保持入口之间的保护等级the equipment and the cable gland, it may be necessary to fit an entry thread sealing washer at the equipment-to-gland entry interface.
The need for a sealing washer will depend on the ingress protection rating, code of protection of the equipment and the type of entry holes available within that equipment. For example, when using Ex e equipment or terminal enclosures (which are permitted to have untapped through-clearance holes) it will be necessary to fit a sealing washer to ensure the minimum IP54 requirement is met. Other equipment with tapped entry holes may not require a sealing washer to maintain the IP54 minimum rating.
CMP recommends using entry thread sealing washers for all installations where an IP rating of IP66-69K is required; these are provided with all polymer TruSeal cable glands.
0 Ring Interface Seals
For the TruSeal metallic range an ‘O’ ring interface seal is provided as standard negating the need for an entry thread sealing washer. ‘O’ rings are rated IP66-69K.
When is it Necessary to Use the TSZ or TSX EMC TruSeal Cable Glands?
电气系统的接地和金属结构,它们可以接触到安全性至关重要。使用编织装甲电缆时,电缆的任何金属部分都应该是接地的,这通常是通过盔甲终止实现的。在情况下,电缆装甲本身未终止时,可以使用“连续性洗衣机”来维持强大的地球。因此,这些接地部件必须能够满足相关电缆的最小短路故障电流。
