Hazardex 2017 Awards - 3. Best User Application - 3A.CCG QuickStop Injection Resin Barrier Gland

20 January 2017

CCG’s QuickStop-Ex Barrier Gland, with an instant mixing and injecting resin, has all but eliminated the problems surrounding the preparing, mixing and applying of compounds/resins in Barrier Glands. The QuickStop-Ex Injection Resin system is instantly and 100% accurately mixed, whilst being simultaneously injected into the barrier gland in one single action.

Challenge

For a number of years installers in hazardous areas have been relying on barrier glands with a two-part epoxy-based putty as a means of stopping explosive gases and liquids from diffusing down unfilled cables.

The mixing process can take several minutes depending on the volume of putty required and the insertion of the putty between the individual cores of multi core cable. This is not only time consuming but there could be additional risks in that the putty may not have been mixed correctly or packed correctly around the cable conductors, which could result in the potential of voids and gaps for gas or liquids to migrate through.

In addition, once the putty has been inserted between the cable cores and the barrier chamber, the time taken for the putty to harden can be up to several hours.

Because of these premixing application and installation problems, barrier glands have always required special skills from the installers and particular attention from inspectors. In addition there has been some recent debate and confusion around the selection and use of barrier glands in relation to the latest IEC 60079-14 standard, with the HSE releasing a safety notice to this effect. 

Solution

CCG’s QuickStop-ExTM Barrier Gland, with an instant mixing and injecting resin, has all but eliminated the problems surrounding the preparing, mixing and applying of compounds/resins in Barrier Glands. The QuickStop-Ex Injection Resin system is instantly and 100% accurately mixed, whilst being simultaneously injected into the barrier gland in one single action.

This reduces the installation time substantially and gives the installer an increased confidence in the installation compared to the epoxy putty or sachet mix liquid pour resins.

The Injection resin flows into all the cable voids and interstices, completely filling the cable end. This forms a 100% barrier to any migration of explosive gases or fluids down the inside of unfilled hygroscopic cables significantly improving on the safety of barrier glands used in hazardous areas.

Ease Of Use
QuickStop-Ex Injection Resin is held in 2-injection syringes and with a vortex mixing nozzle it requires just one hand to mix and apply. Unlike the two part putty or sachet mix liquid resins requiring two hands to laboriously mix.

Instant Accurate Mixing and Simultaneous Injection
QuickStop-Ex Injection Resin is instantly and accurately mixed and then simultaneously injected in just one action through the vortex mixing nozzle, completely eliminating the time taken as well as the risks involved which are prevalent when premixing other forms of resins.

100% Safe And Effective
QuickStop-Ex liquid resin flows into and fills all the voids in unfilled multi core cables displacing all air and guaranteeing a 100% perfect gas and moisture barrier seal. Unlike traditional putty filled barrier glands requiring specialized skill and care to install.

Quick Setting
QuickStop-Ex Resin sets in minutes at 20°C it takes 15 minutes to set and at 30°C it takes just 10 minutes. Compared to 2-3 hours for an epoxy putty barrier gland.

Longer Shelf Life
Because the QuickStop-Ex Injection Resin is held in two separate mixing tubes, there is no risk of diffusion between the resin and the activator, as in the case with a sachet mix system. Therefore, there are no cumbersome cold storage requirements so has a subsequently longer shelf life.

Testimonials from companies such as Aker Solutions, BJC, EPT, EXTech, LaingO’Rourke and many more, available on the company website, attest to the efficacity of QuickStop-ExTM Resin.
