[RE-wrenches] 1,000 volt-rated connectors

[Matthew Sirum]

Greetings Marco,

It sounds like you are likely looking for a 1000V version of something
like the Polaris insulated tap connectors and insulated multi cable
connector blocks or the Burndy insulated multiple tap connectors
(Unitap)...  I believe these all are only 600V rated.  There are still
some gaps in the product offerings available for the 600V to 2kV PV
balance of system needs.  There are some products we may be tempted to
use which may have a 1000V rating, but are only for 1000V use in sign
and fixture circuits.  Other items with sufficient voltage ratings may
be designed for use in the generation and transmission segment of
medium voltage work.  Some of this gear will be made for isolation,
not insulated.... and likely far from appropriate and workable for our
needs.

Depending on the types, gauges, and quantities of conductors you are
working with as well as the required ampacity and intended
installation location some of these products/links may be helpful:

Erico/Pentair makes some useful options including 1000V AC/DC UL din
rail mountable power distribution blocks.  Some of these are being
specifically marketed to the solar PV industry.
https://www.erico.com/catalog/literature/P1215C-WWEN.pdf

Mersen/Ferraz Shawmut offers some 1000V AC/DC power distribution
blocks, some rated for fine strand conductors.

Marathon Special Products has a variety of offerings including 1500V
AC/DC power distribution blocks and markets to the PV industry.

TE Connectivity/Raychem (Tyco) 1000V GTAP products
http://www.te.com/usa-en/product-566427-000.html#guest-click

Some Easy-Splice products are 1000V rated. (These look like the TE
Connectivity GTAP products.)
http://www.nsiindustries.com/catalog/nsiproducts/insulating-splicing-id-products-and-panel-channel/easy-splice™-gel-splicing-kits

SolarBOS (http://www.solarbos.com/), Bentek (http://www.bentek.com/),
and Shoals Technologies Group (http://shoals.com/) all offer 1000V PV
wire connectors, "Y", "T", & "X" harnesses, and inline fuse holders.

Depending on the specific circumstances of the project you may be able
to use 1000V or 1500V PV lead branch connectors to make up the
connection detail you are working on.  Many of the PV lead connector
manufacturers offer these to mate up with the commonly used
connectors.

I hope some of this information may be helpful.  Let us know if you
find 1000V rated insulated multi port tap/splice type connectors or
anything else interesting and useful.

Best regards,

----MATT

Aloha.

Does anyone know of any 1,000 volt-rated insulated connectors?

I checked the Polaris line but they're only rated to 600V.

Mahalo,
