Raychem Screened, Separable<br />
Connection System 630A up to 24kV<br />
The RSTI-L range of screened separable elbows from<br />
Raychem will accommodate cables up to 24kV from<br />
25mm² – 300mm² which covers the majority of<br />
what’s commonly used in New Zealand.<br />
The insulation of the connector is made of a highly<br />
modified silicone rubber characterised by high<br />
tracking resistance, elongation at break and nonflammability.<br />
A thin-walled screen is permanently<br />
bonded onto the insulation and protects the<br />
connection system against unintentional contact.<br />
Oversheath testing can be done with the screened<br />
connector still in place and the termination can be<br />
made with either mechanical or DIN lugs.<br />
With few accessories required for system test,<br />
double “T” and earth connection, an easily accessible<br />
rear plug with capacitive test point, the wide<br />
application range up to 300mm² and exceeding<br />
requirements of CENELEC (includes BS, VDE and<br />
other international specifications), this elbow range is<br />
second to none. Other sizes and voltages also<br />
available.<br />
1. screened body<br />
A thin-walled conductive outer screen is permanently<br />
bonded to the silicone rubber insulating material of the<br />
body.<br />
2. Inner screen<br />
A conductive inner layer, as a faraday cage around the<br />
compression or mechanical lug, prevents corona at<br />
rated voltage.<br />
3. compression or mechanical lugs<br />
Specially designed DIN (see detail below) and deep indent<br />
compression lugs, as well as mechanical lugs with shear<br />
bolts for connecting either aluminium or copper<br />
conductor cables.<br />
4. stress cone adapter<br />
Relieves electrical stress at the point where the cable<br />
screen is cut. The insulated section, extending beyond<br />
the wire shielding, provides a convenient point for<br />
oversheath testing.<br />
5. earthing eye and ground lead<br />
Provides a connection point for earthing the screen.<br />
6. Threaded pin<br />
A threaded pin together with a spring washer and hex<br />
nut ensure a high-performance electrical and<br />
mechanical contact with the bushing.<br />
7. Rear plug with test point<br />
Removable rear plug with capacitive test point.<br />
8. Test point<br />
The test point is used to determine whether the circuit is<br />
energised; alternatively it can be used for phasing.<br />
9. conductive endcap<br />
Electrical screen and protection of the rear end of the<br />
separable connector<br />

Does your Cable Cover Measure Up?<br />
Transnet cable cover, manufactured by<br />
Astron Plastics is:<br />
• Made in NZ from recycled plastic with a high HDPE<br />
content<br />
• No residues or used plastics are included, only clean<br />
post manufacture scrap<br />
• No domestic post consumer waste is used so no<br />
contaminants<br />
• The scrap plastic is collected from around the<br />
country and recycled at one of two Astron recycling<br />
warehouses, Auckland or Christchurch<br />
• The high content of HDPE in our Cable Cover means<br />
it’s consistently strong at a minimal thickness to<br />
conform to AS/NZ 4702 standard<br />
• Being thinner also makes it lighter, reducing the<br />
chance of strain injuries and fatigue for workers<br />
• The Astron factory is ISO 9001 accredited<br />
• We have the ability to manufacture custom sizes up<br />
to 500mm wide<br />
• All batches are tested and test samples are stored<br />
inhouse<br />
• As well as in-house testing, our cable cover is tested<br />
at an independant laboratory<br />
Lighter, thinner, stronger...<br />
the more HdPe content<br />
in the recycled plastic,<br />
the lighter, thinner but<br />
stronger your cable cover<br />
will be.<br />
As/nZ4702 coMPLIAnT cable cover must,<br />
among other requirements;<br />
• Be consistently strong throughout the body of<br />
the product.<br />
• Show manufacturer, supplier and applicable standard on<br />
the top laminate.<br />
• Pass a penetration test allowing no more than<br />
50mm penetration.<br />
‘It’s not<br />
about how<br />
thick it is –<br />
it’s about<br />
how strong<br />
it is’.<br />

Get the right gear<br />
for your job<br />
what’s involved in choosing the right Insulator?<br />
• Determining the Network BIL and Creepage Requirements<br />
Both these values assist in selecting the correct insulator for your application.<br />
• Determining Pollution Levels<br />
All networks experience different pollution levels and this must be determined in<br />
order to select the best insulator to cope with the level of pollution expected.<br />
Pin or Post?<br />
• Dependant on whether you require a Class A (non-puncturable) or Class B<br />
(puncturable) structure. The difference is based on the length of the puncture path<br />
through solid material. Cost can be a factor in this decision.<br />
• Pin insulators are Class B insulators because they are puncturable due to their<br />
design.<br />
• Post insulators are Class A insulators, non-puncturable by design, they have a<br />
puncture path at least equal to half the arcing distance.<br />
• Cantilever strength of post insulators is better than pin insulators because the<br />
insulator sits flat on the crossarm with a large surface area taking any stress.<br />
ceramic or Polymer?<br />
• Depending on the application and the requirements of the network the choice will<br />
be made between Ceramic and Polymer.<br />
• Ceramic insulators are not vulnerable to UV, ozone or rain degradation<br />
• Ceramic insulators are not damaged by tracking<br />
• Polymer insulators are light weight in comparison to their ceramic alternative.<br />
• Polymer insulators offer a hydrophobic housing and superior electrical<br />
performance.<br />
Qualities to consider are; weight, cost, physical size, likely pollution, pin or post<br />
requirement.<br />
International standards Required by the network<br />
• All TE products are tested to various international standards such as ANSI C29,<br />
IEC 60720, BS137 AND IEC 60672<br />
• Warranty Period<br />
— TE has always stood behind their products, whether there is a written<br />
agreement or warranty in place.<br />
— All TE ceramic insulators come with a standard 30yr replacement warranty,<br />
we are happy to discuss and implement specific warranty time with individual<br />
customers.<br />
• TE have manufactured high quality ceramic insulators for 98 years and intend to<br />
continue manufacturing high quality products for centuries to come.<br />

TE Surge Arrestors<br />
With the main design criteria already addressed, this being that<br />
surge arrestors have one main objective – to limit the excessive<br />
overvoltages that occur on the network from damaging<br />
substations, plant and equipment through lightning and<br />
switching errors. TE has also incorporated in the design, some<br />
additional benefits that other arrestors in the market don’t<br />
offer.<br />
Through their material scientists, TE has developed a special<br />
polymer, and this coupled with the innovative wrap design<br />
means that TE can produce a product that has superior<br />
protection against moisture ingress, resistance to insulation<br />
aging and deterioration whilst maintaining consistent<br />
mechanical strength.<br />
TE has also developed a non-explosive disconnect mechanism,<br />
which means no hazardous goods licence is required for<br />
transportation and also offers a safe failure mode for added<br />
protection of workers.<br />
We stock both class 1 and 2 surge arrestors across all voltage<br />
classes used by Utilities. Higher voltages are available, please<br />
contact your local rep for further information.<br />
