An example is to start by creating a narrow ditch (appropriate depth depends on whether the cable is being placed under soil, concrete, etc.).

There are many methods to install a cable underground, reference the NEC Article 300 prior to installing. Overall, direct-burial cable supports a much faster and easier installation (with less material and time required). When it’s time to install, two separate labor expenses are involved: one for conduit installation and an additional cost to install and pull the cable through. In these situations, two separate costs are incurred: cable material expenses and conduit material expenses. If you need to run cable underground, but choose not to use direct-burial cable, then conduit is required. Using conduit will protect your cables & signals underground-however, it adds another layer of complexity and cost to your project.

To put it simply: If you don’t want to use conduit in your installation, then using a cable with a direct-burial rating is a must. Featuring a rugged jacket, the cable can survive being stepped on, being installed on top of rock or having long-term contact with water-without tearing or negative impact on the performance. To make the “direct burial” claim, third-party testing and ratings are necessary to verify that the cable has the mechanical properties necessary to withstand the rigors of being used in outdoor, underground applications.Ĭonstructed almost as if it has its own, built-in conduit for crush resistance, direct-burial cable is thoroughly tested to pass the same mechanical stresses a typical conduit endures.

It also must be PLTC-rated which includes passing the UL 1685 flame test.

A copper data cable that gets wet does not work! Underground burial cable type also lacks the mechanical strength necessary for underground direct burial.ĭirect-burial cable is a UL rating earned once a cable passes insulation water absorption and crush-resistance tests. The distance between the two conductors in a pair and the shields is critical to the overall cable balance in regards to NEXT and RL performance which affects system stability. Wet data cable changes the electrical characteristics of the cable as it introduces another conductive element, water, between each pair or singles. If a data cable gets wet, it will have higher attenuation which may impact performance in the field. In general, PE cable jacket has better water resistance than PVC jacket, CPE cable jacket is even higher in water resistance than PE jacket. Water-blocking fillers or polymer gel are designed to stop infiltration in an underground burial cable, but the jacket might not be water resistant over a prolonged period of time water can ultimately migrate to the core of the cable if exposure lasts long enough. Without this protection, the cable can’t withstand underground exposure. Underground burial cable can be installed underground-if it sits inside conduit. It withstands moisture and high and low temperatures, and resists abrasion and tearing-but isn’t designed to be directly buried underground. Outdoor cable features outdoor ratings and maintains performance despite harsh conditions. Let’s take a closer look at three types of cable often considered for outdoor applications. The cottage is a credit to Judith the owner.Three cable types normally rise to the surface in discussions about outdoor installation:īut not every cable that is outdoor-rated or says “burial-rated” can be directly buried underground with no protection. We used Margaret's Cottage as base from which to explore the surrounding sites of this part of Wales and would highly recommend it. There's a local pub also in walking distance but I suggest phoning ahead to check if they are actually serving food as quiz night seems to be much more important ha hah. The large bath was also a treat.īerry Port is a short downhill stroll and the walkway around the coast is very enjoyable. The cottage is deceptively large and the main bedroom has a huge comfortable bed which also enjoys the amazing view.

The owner really knows how to look after her guests and was always available pre-arrival to answer any questions and point us in the right direction.

A real home from home but with locally produced welcome gifts on arrival. An amazing view across Berry Port to the beach and out to sea, a fantastic patio on which to enjoy meals and drinks, and a cottage packed with everything one could ever need. We (2 adults and a 7 year old) stayed at Margaret's cottage for 5 nights at the end of August.
