SIMTRA Cables allow electrical power to be
commingled with any low voltage
communication circuit within one conduit or
pathway. Our innovative design allows the
installer to pull all wiring in a single run while
simultaneously integrating all electrical
systems, reducing materials and labor costs.
SIMTRA Cables are ideal for all-in-one power
+ communication cabling installations and
solutions.
SIMTRA Power Cable is a Type TC or Type NM-B ULListed Cable. What makes SIMTRA unique is the
Ferrite Barrier that surrounds the power conductors.

What is the SIMTRA technology?
The SIMTRA Cable incorporates a Ferrite Barrier
which has the ability to reduce and absorb electrical
transients, interference and/or disturbances imposed
on or emanating from that cable.
What is Ferrite?
Ferrite is composed of iron oxide (Fe2O3) combined
chemically with one or more additional metallic elements.
They are ferromagnetic, meaning they can be magnetized
or attracted to a magnet, and are electrically
nonconductive.

Electrical Fast Transient Spike
Bit Error Test
•
Multiple Electrical Fast Transient (EFT) spikes at 500V, 100V, 2500V and 4400V were
injected onto the line, neutral and ground conductors on the SIMTRA Ferrite Barrier
Power Cable and compared to standard NMB cable and THHN wires.
•
Simultaneously, data bits at 100 mega bits per second (100 Mb/s) and at 1 giga bit
per second (1 Gb/s) were transmitted onto various different 100 Mb/s rated Ethernet
5e cable and monitored for bit errors. Data transfer test duration time was 6.1
minutes out of 7 minute test. Therefore at 100 Mb/s there were 36,600,000,000 bits
transferred at 1 Gb/s there were 366,000,000,000 bits transferred.
Definition:
If 100 M=100 x 106= 100,000,000 therefore 100 Mb/s= 100,000,000 b/s
If 1 G= 1 x 109= 1,000,000,000 therefore 1 Gb/s+ 1,000,000,000 b/s
And if there are 60 seconds (s) in one minute:
There are 366 seconds in 6.1 minutes
There are 36,600,000,000 b/s for 100 Mb/s transmitted and
There are 366,000,000,000 b/s for 1 Gb/s transmitted
Electrical Fast Transient Spike
Bit Error Test
•
The purpose of this testing was to determine how the levels of fast transients as
outlined in the standard BS EN 61000-4-4:2007 with variations in the voltage levels
on the power cables affected the data in the Cat5E cables.
•
Note that 500V is the level most Electromagnetic Compatibility (EMC) product
family/specific standards call out for EFT on Input/Output (I/O) lines. For equipment
used in industrial locations, sometimes 1kV is called out for EFT on I/O lines, but
never higher than that. Power lines are sometimes required to be tested up to 2kV,
but not I/O lines. The transient levels tested were representative and in excess of the
environment typically found in commercial buildings.
•
Regarding the performance criteria for I/O lines, most EMC product family/specific
standards allow that the Equipment Under Test (EUT) may experience degradation of
performance, such as bit errors, during the EFT disturbance, but must return to
normal operation on its own, without manual intervention, after the disturbance. It is
typically not specified that the EUT operate error-free at any EFT test level.
•
Generally, high voltage and/or high speed EFT occurs on AC power lines and can
enter a system through capacitive coupling or supply injection. The source can be a
noisy motor generator or any other similar source that may unintentionally emit EFT
either continuously or intermittently.

BIT Error Test Results
The SIMTRA Ferrite Barrier Power Cable out performed the standard NMB cable

Important to Note:
Appropriate data cable selection is
essential to, and linked to its application
use and cable performance.
Note 1:

each data cable was from three different
manufacturers.
Note 2:
BIT Errors occurred before testing even
began on one particular data cable under
the 1 Gb/s data transfer before the EFT
(electricalfast) testing began.
Errors accumulated faster indicating that
the 5e data cable selected for this test was
not rated for 1 Gb/s Ethernet traffic and/or
exceeded the maximum length to support. Rule:

Insertion Loss Test
•
A signal generator was used to transmit a 20dBm signal at various
frequencies from 0.5MHz to 1GHz. A spectrum analyzer was used to record
the signal received. The spectrum analyzer readings with the insertion of
330ft of Simtra Cable were recorded. The differences in the measurements
with and without the insertion of the cable were calculated. The spectrum
analyzer input port was set with a 50 Ohm termination. The data cable was
terminated at a Bit Error Rate Tester (BERT) which transmitted data
at 100Mbps and 1000Mbps. The purpose of this test was to do a
comparison between the insertion loss readings for all cables.
•
Insertion Loss readings were taken between the 0.5 - 1000MHz frequency
range. The table below shows the readings obtained for the Simtra cable.
The Insertion Loss Test graph below shows a comparison chart.
•
The Simtra Cable exhibited no degradation of data transmission. The
Ethernet traffic was not affected by the 20dBmsignal running through the
power cable at both data speeds. The Simtra Power Cable attenuated the
20dBm signal at 0.5MHz through 1000MHz as shown on Table below under
the Insertion Loss column.

Voltage Coupling
•
During the coupled transient surge testing, a transient with known waveform
and voltage was injected into the power cable. The transient seen on the
data cable that was skip bound along with the power cable was measured.
•
The purpose of this test was to determine how much of the transients sent
through the respective power cable gets coupled onto the data cable that is
skip bound together. During the coupled transient surge testing, the test
equipment will inject a transient with known waveform and voltage into the
power cable. An oscilloscope will measure the transient seen on the data
cable that is tied along with the power cable.
•
The Simtra Cable exhibited no degradation of data transmission. Ethernet
traffic was not affected during all transient surges. The voltage coupling onto
the data cable from various transient surges representing a lightning strike
or short circuit induced on the power cable had excellent surge suppression
characteristics. The ferrite absorbed practically the entire transient surge of
500V, 1000V and 2500V only allowing less than 1 volt levels to couple over
to the data cable.

Randazzo continues. “ When you include the cost of the conduit and
installation, you are looking at a savings of 60 percent.”
