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

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

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

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