The shielded cable can protects the signal from external interference. As we know, Cables can be a main source of transfer for EMI, both as a source and receiver. As a source, the cable can either conduct noise to other equipment or act as an antenna radiating noise. As a receiver, the cable can pick up EMI radiated from other sources. A shield works on both. The cable with shields ability can maintain signal integrity in a noisy environment, such as airport, factory etc.

Different type of shielded cable

There are three most common shielded cable, Braid Shield ( e.g coaxial cable), Spiral Shield (e.g some audio cable), Foil Shielding (e.g some coaxial cable)

Braid shield

Spiral Shield

The spiral shield consists of wire (usually copper) wrapped in a spiral around the inner conductor wire.

Foil Shields

It consist of aluminum foil laminated to a polyester or polypropylene film. The film gives the shield mechanical strength and bonus insulation. Foil shields provide 100% cable coverage, necessary for electrostatic shield protection. Because of their small size, foil shields are commonly used to shield individual pairs of multi-pair data cables to reduce crosstalk. 

The feature of different shielded cable

Shield Type	Advantage	Disadvantage
Braid Shield	Braid shields provide superior structural integrity,e ideal for minimizing low frequency interference and have lower dc resistance than foil. Braid shields are effective at audio, as well as FR ranges. Generally, the higher the braid coverage, the more effective the shield.	Braid shields are generally bulkier and heavier than other shields and, in some cases, harder to terminate because the braid must be combed out and pigtailed.The trade-off between cost and braid coverage must be considered.
Spiral Shield	The Spiral Shield provide superior flexibility, requires less copper, much faster and cheaper to manufacture, and is quicker and easier to terminate than a braided shield. They are best choice for audio cables.	Spiral shields are not effective above the audio frequency range due to the coil effect produced by the inductance or served wire strands.
Foil Shield	Foil shields provide 100% cable coverage, necessary for electrostatic shield protection,have less weight, bulk and cost less than spiral or braid shields and are generally more effective than braid shields in FR ranges.	Foil shields have a shorter flex life than spiral or braid, and using the foil shield include higher de-resistance and lower mechanical strength than braid or spiral shields.

Pinouts is the way connecting the contacts on each end of the cable. As we know, contacts in electrical connectors, which will be power- or signaling-related, must be specified in order for connectors to be interchangeable. If contacts of disparate functions are allowed to make contact, the connection may fail and damage may result.

Therefore, to make sure our clients get the right products, pinouts are a key question we ask the clients when they order the connectors, cables, and adapters.

Here are some examples that how you can show us the pinouts you need.

e.g
Drawing

Or even you can draw it like as below, our technician will still get it.

e.g
Wiriting

We will be appreciated that if you can send these pinout to us when you inquiry. However, we will confirm it with you before production to make sure you get the correct products you are looking for.

According to China's Law, our workers will have a short holiday for celebrating the International Worker's Day.

Our holiday schedule is as blow:

1. The Maximum Distance for Power Cable

Note: 

The date in the chart are based on the voltage and power being used.

2. The Maximum Distance for Coaxial Cable

Note:

For Bulk Siamese Cable (RG59 Coaxial cable with 18AWG Power Wire), the limitation for 12V Camera is about 70m (223ft) due to the signal drop.

Due to China Qingming Festival is coming soon, which is the day for mourning the dead in China. We will have a short break.

Our holiday schedule is as blow:
Factory: From 2012/04/03 to 2012/04/04

At first, it is just an idea and it is not a regular DC power splitter.

And as a manufacturer, we give some advices to Mr K based on the view of production, such as the material of the wire etc.

Mr K take our suggestions and then revised the design as below

We know this is a new product for Mr K, and he may have not enough confidence that this idea can come true.

And we don’t want to produce the cables in bulk but the customer can’t use it, too. So we propose that we can make several pcs of sample for him. And to show our sincerity, our sample is free.

Within 1 week, Mr K got the sample, and then they test it, and so get some feedback from their customers.

To get a good market response, Mr K decided to revise the design again, from one size to two sizes. The small one is for Male customer, and the big one is for male customers. So their products can cover all of the customers.

We will have a short holiday to observe the New Year's Day holiday.
Our holiday is from 2011/12/31 to 2012/01/03, Thanks for your attention.

Any inquiries for CCTV Camera Cable, Audio Video Cable, or LED lighting Cables, please leave a message to us by Email or on ourwebsite, we will reply you when we are back to office then.

Wish you success and good luck in the coming new year.

Best regards.
