CATV Series Cables

Leave a comment

Community Antenna Television (CATV) series cables are constructed using Copper Covered Steel Center Conductors (CCS). CCS conductors give strength to CATV series cables when installers pull on the coaxial cables. CATV series cable uses a bonded foil shield with an aluminum braid to prevent high-frequency RF leakage, which can result in fines from the FCC.

A CATV Series cable also shields against low level high frequencies. Syston Cable Technology’s series of broadband and digital coaxial cables are tested to the highest standards to ensure the best performance in high-end home theater installations, incorporating HDTV and digital video.

Coaxial Cables Application

Leave a comment

Coaxial cables or COAX cables are the ideal solution for all applications requiring high speed data and video, flexibility, protection from extreme environment and high and low temperature resistance. Where you need a signal with minimum distortion and attenuation or no interferences, coaxial cables play a pivotal part. In fact, thanks to their twin conductor construction nature, they are able to ward off many issues produced by bifilary wires.

Coaxial cables consist of two copper or aluminium coaxially oriented conductors surrounded by a tubular insulating layer, enclosed by a conducting shield. The quality of coaxial cables affects the signal interference; higher quality ensures a minimum signal interference. Moreover, also the density of the shielding affects the quality of the COAX. The result is that high quality materials and manufacturing process are essential to manufacture a reliable coaxial cable.

Generally, coaxial cables end with connectors that are usually manufactured with high conductivity metals. There are many different kinds of coaxial cables, which are generally defined by electrical capabilities, outer diameter or materials. However, most coaxial cables are manufactured in line with RF industry standards, the American norm MIL-DTL-17 and the French norm NF-C-93550.

An example is represented by RG cables, where the copper and aluminium copper clad wire quality, as well as the foaming extrusion, are part of the efficiency of signal.

Although the solutions for a high quality coaxial cable manufacturing look like straightforward, the design of these lines requires expertise and a deep understanding of the final product. Here, we do not see our intervention as a mere product supplier. Our solid expertise in the field as manufacturer, designer and supplier of these remanufacturing solutions, gives us an holistic understanding and all the know how to optimize the solution based on customer needs and specific industry requirements from the drawing (single wire & multi-wire) to the extrusion (insulation & sheathing), passing through the wire assembling (bunching).

Speaker Cable Connectors Explained

Leave a comment

Any time components need to be connected together, the type of connectors that are used become important. More than anything, designers look for connectors that will provide a secure connection, with low signal loss.

With speaker cable, this problem is amplified over other types of audio and video connections. The signal going to speaker cable is a relatively high powered analog signal. Compared to electrical house current used for appliances, it isn’t all that high, but compared it is much higher than any other audio or video signal used in most systems.

Any analog signal can become distorted if the wire size or connector contact area is not sufficiently large to carry the signal. This is not based upon the signal’s voltage, but rather the signal’s amperage. At the same time, signal loss, which is a reduction in voltage, increases over small wires. This is why many audio consultants recommend large wire gauge sizes for speaker cable, especially on systems which are using high power audio amplifiers.

Even with this clear need for high power capacity, speaker cable connections have been largely ignored, using other types of available connectors, up until recent times. In many cases and for many years, the only electrical connection used for speaker cable was a simple screw terminal with bare wires. While functional, this type of connection is not highly portable or secure. Often, only part of the wire’s strands are captured under the screw, making for poor electrical and mechanical connection.

Fire Alarm Cables

Leave a comment

Fire alarm cable systems serve as a life line and a connection to first responders. When a signal is transmitted to central base, failure is not an option, it must be guaranteed. Faulty or non-signal due to alarm cable failure is the last concern a building owner, tenants, or a city needs.

We manufacture 12 awg to 24 awg bare copper, PVC and Plenum (FPLR / FPLP), shielded, and unshielded. Our alarm cable meets Local Law 5 Fire Alarm cable as well as other municipal specifications.

For your assurances, all Fire Alarm Cable is ETL Listed. With our variety of colors, stripping options and environmental ratings. Fire alarm cable features our EZ peel off jacket that provides a fast and secure installation.

What is a data cables?

Leave a comment

The term data cables stands for “Universal Serial Bus”. Data cables assemblies are some of the most popular cable types available, used mostly to connect computers to peripheral devices such as cameras, camcorders, printers, scanners, and more.

As mentioned above, data cable assemblies are designed with several distinct connector types. The most common types you will see are called Type A and Type B, though you may see “mini-B” connectors with either 4 or 5 pins.

The different connector types have an important strategic purpose to them. They are designed so you can not plug two computers into one another, and you can not plug two peripheral devices in together.

6 Different Types of Fire Alarm Cables

Leave a comment

Fire alarm systems are very important for any business, school, facility, home and much more. They protect us when alerts arise and deliver notification of potential threat and harm. In previous blogs, we have discussed how fire detection systems work and the differences between conventional vs. addressable fire alarm systems.

Today, we will go over the different types of fire alarm cables with both power limited and non-power limited fire alarm cables.

Power limited Fire Alarm Cables

1) FPL which is a power-limited fire alarm riser cable is usually the least expensive because it is the most basic type of fire alarm cable and is also recognized by the NEC (National Electric Code). FPLR cables are suitable for use in a vertical run through a shaft or from floor to floor within a building.

2) FPLR Shielded is a power-limited fire alarm shielded cable, has the same components of the standard FPLR but, includes an aluminum polyester foil shield and drain wire to protect against outside interference.

3) FPLP which is a power limited plenum cable and they are recognized by the NEC for use in air ducts and plenum spaces and any other space that is used for the flow of environmental air. These cables tend to be a little bit more expensive due to the additional engineering and protection they offer. All FPLP cables are listed as having adequate fire-resistant and low-smoke-producing characteristics as well.

4) FPLP Shielded cables are power limited plenum fire alarm cables with an aluminum polyester foil shield and drain wire to block an additional interference within a cable.

Non-Power Limited Fire Alarm Cables

1) NPLF or, non-power limited fire alarm cables are recognized by the NEC and are suitable for all general fire alarm cable uses. They cannot, however, be used in riser, ducts or plenum spaces that used for environmental air flow unless they are properly installed within a conduit.

2) NPLFP are non-power limited fire alarm cables are also recognized by the NEC but these cables are suitable for installation in ducts, plenums and other spaces where environmental air flows.
