Selecting the Right Busbar Insulation: Why Epoxy Coating Powder might be your Best Choice

When it comes to insu­lat­ing bus­bars, there are a num­ber of options avail­able, includ­ing plas­tic-sheath­ing, mylar, and epoxy insu­la­tion. While each option has its own advan­tages, epoxy pow­der-coat­ing is the best choice for ensur­ing the safe­ty, longevi­ty, and cost-effec­tive­ness of your elec­tri­cal instal­la­tion. In this arti­cle, we’ll explore the ben­e­fits of choos­ing epoxy insu­la­tion for your bus­bars and why it’s the ide­al choice for your next project.

Cost Savings

One of the biggest advan­tages of epoxy insu­la­tion is the cost sav­ings it offers. Epoxy is 67% cheap­er per lin­ear meter com­pared to plas­tic-sheath­ing and mylar insu­la­tion. It also has a much high­er max­i­mum oper­at­ing tem­per­a­ture of 180°C com­pared to plas­tic at 93°C. This makes epoxy a great choice when con­sid­er­ing life-cycle cost­ing for your elec­tri­cal installation.

Quality and Durability

Anoth­er key ben­e­fit of epoxy insu­la­tion is its qual­i­ty and dura­bil­i­ty. Epoxy has great dielec­tric strength and per­fect uni­form adhe­sion, mak­ing it great for cov­er­ing com­plex and odd-shaped bus­bars. Its chem­i­cal­ly bond­ed con­for­mal coat­ing elim­i­nates voids and pre­vents mois­ture pen­e­tra­tion, mak­ing it scratch-resis­tant and able to han­dle ther­mal expan­sion and flex stress­es. This ensures your instal­la­tion will last for many years, with min­i­mal main­te­nance required.

Future-proofing Your Installation

With trends show­ing a rise in the aver­age oper­at­ing tem­per­a­ture of pow­er dis­tri­b­u­tion instal­la­tions, it’s essen­tial to choose an insu­la­tion option that can han­dle the increased heat. Epoxy’s high­er max­i­mum oper­at­ing tem­per­a­ture ensures your instal­la­tion is ready for the future, pro­vid­ing you peace of mind and pro­tec­tion against poten­tial damage.

Thermally Conductive Epoxy — The Best Choice

At CAPLINQ, our engi­neers and prod­uct devel­op­ment team have tak­en the best qual­i­ties of epoxy and made it even bet­ter. We’ve devel­oped a new ther­mal­ly con­duc­tive epoxy coat­ing that has over 300% the stan­dard ther­mal con­duc­tiv­i­ty (1.0 W/mK) com­pared to stan­dard epoxy (0.3 W/mK). This increased ther­mal con­duc­tiv­i­ty allows for faster heat loss, which can save on mate­r­i­al weight and cost, and increase effi­cien­cy and over­all longevi­ty of your installation.

Faster heat loss also means you can get the same cur­rent-car­ry­ing capac­i­ty for less mate­r­i­al. Bus­bars can be thin­ner, longer, lighter, and even made of a less con­duc­tive mate­r­i­al when work­ing at low­er tem­per­a­tures. Sav­ing ini­tial instal­la­tion costs and long-term main­te­nance costs.

In Conclusion:

When it comes to insu­lat­ing bus­bars, epoxy pow­der coat­ing is the best choice for ensur­ing the safe­ty, longevi­ty, and cost-effec­tive­ness of your elec­tri­cal instal­la­tion. With its cost sav­ings, qual­i­ty and dura­bil­i­ty, future-proof­ing capa­bil­i­ties, and ther­mal­ly con­duc­tive options, epoxy insu­la­tion is the ide­al choice for your next project. At CAPLINQ, we’re com­mit­ted to pro­vid­ing the best solu­tion for your bus­bar insu­la­tion needs, and we’re con­fi­dent that our epoxy coat­ing is the only real design deci­sion you can make to min­i­mize life-cycle costs and ensure your instal­la­tion is safe, durable, and cost-effective.

Please be sure to explore our whole range of epoxy coat­ing pow­ders includ­ing our halo­gen-free LINQSOL BCP-1504 which is devel­oped specif­i­cal­ly for bus­bar epoxy coat­ing appli­ca­tions includ­ing both low volt­age (<600V) bus­bars as well as medi­um volt­age (up to 38kV) bus­bar appli­ca­tions.

We have also intro­duced pow­ders such as LINQSOL BCP1507 and LINQSOL BCP1509 have been proven to coat thick under var­i­ous temperatures.
